The episode kicks off with a police dispatcher's voice echoing through the airwaves, as a couple lies prone on the ground, seemingly lifeless. Suddenly, the woman stirs from her apparent slumber. Elsewhere, Sunny Patel (Agam Darshi) reveals to Kye (Ennis Esmer) a chilling video of herself engaging in sleepwalking. Intrigued, she promptly requests to view the surveillance footage of their building. Kye obliges, logging into the computer system to display the footage, which merely shows Sunny entering and promptly exiting an elevator. Their discussion is abruptly halted when Tess Avery (Dolly Lewis) places a call.
Sunny then navigates Tess through what transpires to be a tumultuous protest. Amidst the throng, Tess becomes disoriented and struggles to hear Sunny's instructions. The scene descends into chaos as the police arrive, unleashing pepper spray indiscriminately. Just then, Matt Alleyne (Jarord Joseph) arrives on the scene and steers Tess to safety. Matt fills Tess in on the officer's excessive force, prompting her to vow to address the issue with Superintendent Bennett (Roger Cross).
Jake Campbell (Daniel Gillies) guides Tess through the crime scene, detailing the victims' plight. When Jake speculates that poison was likely used in the attack, Tess hypothesizes that the perpetrator could be among the staff or guests. Upon discovering that the protesters had occupied the building, Sunny directs Tess towards the emergency exit hidden in the kitchen. As she swings open the door, an alarm blares to life, but her attention is drawn to a sticky residue clinging to the latch. She surmises that someone might have deliberately deactivated the alarm and reactivated it once the protesters had vacated the premises.
At the hospital, Tracy recalls no alarm during the protesters' raid. Instead, her ears were assailed by a cacophony of obscenities and shouting.
Back at the precinct, Detective Leo Li (portrayed by Tony Giroux) deliberately drops the hint that Jake is being reassigned to a special duty the following week. Barely had the words left his lips when Leo's phone buzzed with a message from campus security, informing him that surveillance footage had uncovered one protester masquerading as a caterer and tampering with the food.
When Tess confronts Jude (embodied by Madonna Gonzalez), Jude confesses to propping the door open for the protesters but adamantly denies the poisoning. She further admits to acquiring a badge from a Kith and Kin adherent using the screen name 'Truthseeke25.' Their discussion is abruptly cut short as someone ignites a fire behind Tess using the protest signs as fuel.
After Tess indulges in a refreshing swim, she turns to Matt for assistance with the Kith and Kin lead. He willingly agrees to delve into it but inquiries about the officer involved in the protest. Tess informs him that the incident is under review and the officer will most likely face disciplinary action. Their conversation stalls again as Tess receives a call from Jake.
Jake informs Tess that Gavin was poisoned with strychnine. The complicating factor is that no traces were discovered in the food, beverages, or within the campus dining hall. He also unveils the contents of Gavin's office on campus. While perusing through the items, Tess attempts to discuss Jake's transfer with him. He reveals that it's an undercover mission that could keep him away for six months. When he seeks her opinion on his departure, she tells him he must do what's best for his career. Before the conversation delves deeper, Tess realizes that strychnine has a bitter taste and would necessitate something potent to mask it.
Back at the hospital, Tracy confesses to both her and Gavin being addicted to breath mints. She asserts that if they were tampered with, it must have occurred before lunch since they were confined in Gavin's office. The only individuals with access were Tracy, Gavin, Samantha 'Sam' Sinclair (played by Helena Marie), and Phil. Shortly thereafter, Sam arrives and advises Tracy to speak at Gavin's funeral. Tess and Sam clash, prompting Tess and Jake to question her in private.
Shortly thereafter, Jake came to the startling realization that Gavin and Tracy's seemingly innocent breath mints had been tampered with, laced with poison. Rae (Tegan Moss), in her meticulous investigation, uncovered carbon residue in the coffee cup, promptly sending it off for in-depth analysis. At the precinct, Tess was rocked to learn that Matt had released footage of an officer apprehending a protester during the riot. Matt, unapologetic, justified his actions, asserting that exposure was preferable to discipline. Their heated debate was interrupted when Sunny observed that the footage also captured Phil amidst the protesters.
While awaiting Jake's return with Phil for interrogation, Tess and Sunny delved into the stark contrast between Phil's ideals and those of Truthseeker25. Additionally, Sunny unearthed fascinating sociology essays penned by Tracy during her college years, ultimately revealing that she had authored Gavin's speeches. Leveraging this newfound knowledge alongside their case insights, they gained access to Truthseeker25's social media account. Intriguingly, the day preceding Gavin's demise, Truthseeker25 had vowed to "cut the head of the snake."
Under questioning, Phil confessed that both he and Gavin were Truthseeker25, admitting they orchestrated the protest to garner donations. He further admitted to visiting the Kith and Kin office and noticing an emptied account, speculating that Gavin knew the perpetrator and intended to confront them.
Following Phil's interrogation, Jake and Tess devised a strategy of division and conquest. Jake took charge of Gavin's emails and texts, while Tess tackled Kith and Kin's financial records. As Tess and Sunny pored over the financial data, they made a bombshell discovery: Sam and Gavin were responsible for the withdrawal.
Sunny ingeniously rigged her door to topple a bucket filled with nickels, serving as an alarm to rouse her from any sleepwalking escapades. When the clamor awakened her, she was met with the echoing yells reverberating down the hallway. Alerting Kye to the commotion, he ventured out to investigate but returned empty-handed.
After confiding in Jake about her unusual wake-up call, he and Tess pieced together the puzzle, deducing that Sam and Gavin were entangled in an affair. Tess, later sharing this revelation with Tracy, discovered that Tracy had been privy to the secret all along; she just hadn't known the identities of the lovers until now. As Tess and Tracy continued their conversation, Tess received a call. Taking advantage of Tracy's temporary absence, Sunny stealthily directed Tess to a nearby wastebasket, where a book lay hidden. It was "Family" by Louis Gasson, bearing an inscription from Sam that read, "From our college library where it all started, to better days."
Upon Tracy's return, Tess learned that Sam was in Gavin's office, making arrangements for the funeral. By the time Tess arrived, Sam had vanished, leaving behind her purse. Inside, Tess found a letter and a packet of breath mints, clues that unveiled Tracy's sinister plot—she had poisoned Gavin and herself, and her next target appeared to be Sam. In a hurry, Tess contacted Jake.
Despite the police's extensive search, Sam remained elusive at her apartment, relatives', and Kith and Kin. Tess recalled the library book and its message, realizing Tracy might have lured Sam to the library. Rushing to the library to save Sam, Tess was paralleled by Tracy, who went live with the funeral broadcast of Gavin. After some searching, Tess finally found Sam, unconscious and barely alive from being drugged. Concurrently, Jake apprehended Tracy on live television.
Tess offered an apology to Matt, which he graciously accepted, mending their rift. Later that evening, Jake visited Tess at her home to inform her of his transfer. Though she beseeched him to stay, he insisted that he needed to find a way to move forward since he felt he was no longer keeping pace with her. Despite their heartfelt conversation, they couldn't resist sharing a kiss.
Sunny was once again awakened by the haunting screams that had disrupted her peace the previous night. Swiftly, she logged into Kye's account on her computer to scrutinize the surveillance feeds. Kye sat at his desk, unaware of the approaching shadow creeping into view. The episode concluded with this cliffhanger, leaving the viewer on edge.
