At the opulent Belvor Estates, a man is suddenly felled by a gunshot, disrupting the serene ambiance. Meanwhile, Will is being meticulously outfitted in a pristine white tuxedo, as he prepares to escort Faith and Jeremy to a lavish wedding. A wedding novice, Will's dashing appearance earns him comparisons to James Bond from an admiring Faith. Embracing his Bond-like persona, Will vows to elevate Faith's confidence, sensing her anxiety about her friend Lindsay's habitual condescension.
Amidst the opulent wedding revelry, they chance upon Jeremy and Faith's acquaintance, Danielle, who inadvertently lets slip that Jeremy has embarked on a new career path. Jeremy reveals his role as a sound engineer, omitting the crucial detail that he left college to pursue this passion. Will steps in to smooth over the unfolding tension, suggesting Faith take a breather with him while Jeremy searches for his groomsman, Colin, for their photo shoot.
Just when Faith thinks her day couldn't get any worse, a clumsy guest dumps a drink onto her brand-new dress, staining it prominently. Will, ever the smooth operator, gently ushers her away from the escalating embarrassment, leading her upstairs to address the stain with discretion.
Jeremy encounters his friends in the dimly lit basement, where they stumble upon a grim discovery: a lifeless body lying still. Suddenly, a gunman trains his weapon on them, the barrel gleaming ominously in the dim light. As Will highlights Faith's virtues, an ear-piercing scream tears through the silence, signaling an active shooter on the loose.
With cautious steps, they inch their way down the stairs, every sound amplified in their heightened state of awareness. Their eyes fall upon multiple gunmen, who hold the helpless guests hostage with cold precision. These perpetrators demand phones, purses, and money with callous disregard. One of them spots Will and commands him to descend the stairs slowly, hands raised in surrender. Meanwhile, Faith finds refuge in the secluded safety of a bathroom, while Will joins Jeremy and their friends, his mind reeling with memories.
Haunted by visions of Sleeveless Jack murdering his wife and comforting the terrified children, Will struggles to mask his trauma as he reassures Jeremy of their eventual safety. Overhearing snippets of the gunmen's conversation, Jeremy reveals the body they found and speculates about a safe they might have been attempting to breach. Will posits that the intruders hadn't anticipated encountering people, rendering the hostages an unwelcome complication. Patty, a worried hostage, inquires about their plan, which revolves around keeping a low profile.
In a flashback-interrupted moment, Will approaches the gunmen with a bold suggestion: moving the corpse might alleviate the hostages' distress. The leader, intrigued, allows Trey to escort Will and Jeremy for this task. As they cover the deceased, Will engages Dominique with a sarcastic remark, probing if he's enjoying himself. The gunmen are skeptical of Will's facade, yet he manages to convince Dominique of his legal prowess, hinting at a future collaboration that could keep him out of jail—since Dominique has yet to take a life.
Playing his part with seamless fluidity, Will then suggests Jeremy fetch some snacks for the upstairs hostages. Elsewhere, Angie and Michael pore over case notes at the bustling bar where Crystal works. Angie's late arrival, attributed to a school project, seems to please her, but Michael remains skeptical, sensing her deception and believing she should delve deeper into the investigation.
Faith rummages through the assorted gifts in a desperate hunt for a firearm. Eventually, she stumbles upon a collection of decorative stones and, making do, stuffs them into a sock. Christian, the waiter, catches sight of her, but their confrontation is abruptly interrupted by a crackling report over the walkie-talkie about a missing guest. In the ensuing scuffle, he lunges at her, only to be met with the sharp tip of a fondue fork wielded by Faith in self-defense. Terrified yet unwavering in her resolve to salvage the wedding, Faith catches a glimpse of a fax machine and seizes an opportunity.
Angie reprimands a customer for laying a hand on Crystal, subsequently scolding Crystal herself for her flirtatious behavior towards the patrons. Meanwhile, Faith attempts to discreetly signal Jeremy to toss her a pen, but the plan misfires as the pen's landing draws the shooter's attention. Stede informs their leader of Christian's – the safecracker's – demise amidst their contentious squabble and physical altercation.
Jeremy, spotting Will, hastily communicates that Faith is alive and in desperate need of a pen. Will, swiftly procuring one, also requests Miss Patty's inhaler and urges her to feign an asthma attack, buying him precious time. Pretending urgency, Will announces his need to fetch the inhaler upstairs lest Miss Patty perish, then makes his way to Faith, who eagerly awaits to fax a message to the Austin Police Department.
Concurrently, Will endeavors to persuade Dominique to abandon their plans, while Stede searches the upstairs bathroom and discovers Faith's purse. Suddenly, dance music blares through the walkie-talkie, creating a diversion that enables Faith to fell Stede with a well-placed blow to the head, initiating a fierce struggle between the two women.
Downstairs, Will nearly succeeds in convincing Dominique, but Trey's sudden and fatal shot silences her. The sound of the gunshot jogs a haunting memory from Will's childhood.
Trey selects Colin, Jeremy's friend, to accompany them into the vault. Upon glimpsing Jeremy's photograph, Stede's voice booms, demanding Faith's immediate presence or Jeremy's life will be forfeit. This demand inflames Faith's temper. The APD captain, at last, catches sight of Faith's fax and urgently commands the search for Amanda, Angie, and Michael. Upon their arrival, Angie and Franklin persuade Amanda to despatch a small reconnaissance team.
Will, pleading for mercy towards Colin, meticulously inspects the safe, which sports a dial lock akin to an intricate gear engine. His mind drifts back to haunting flashbacks of his twelve-year-old self while Stede's threats loom over Faith and Jeremy's lives.
Faith and Jeremy find themselves imprisoned. She confesses her sole aspiration was to secure a better life for Jeremy than she had known. Stede's return prompts Faith to coerce Jeremy into pressing a button, triggering an alarm, unlocking the door, and igniting another fierce confrontation with Stede.
Will's desperation escalates, his pleas for more time intertwined with poignant memories of Sleeveless Jack taking his wife's life. In a heart-wrenching scene, Will is seen sobbing beside her lifeless body.
Chaos ensues as Chas bursts in with guns blazing, while Will aims his weapon at Trey as the APD arrives. Angie urges immediate medical attention for Faith, but she insists on her well-being and reveals Stede's whereabouts in the kitchen. Angie enquires about Will's whereabouts, only to discover him with Mike and a hysterical Colin.
Back at the office, Amanda and Faith achieve a long-overdue reconciliation. Angie arrives to escort Will home, acknowledging his need for companionship. As his emotional dam bursts, they embrace, marking their rekindled romance.
