The second episode of "Toxic Town" unfolds with a leap through time, revealing Susan's son, now slightly older, grappling with persistent skin afflictions and undergoing numerous surgeries. An investigative journalist reaches out to Susan, hoping to shed light on her ordeal, but she resolutely declines, unwilling to reopen wounds long scarred over. As her son's struggles continue, Susan takes him to a specialist who suggests cosmetic procedures to alleviate Connor's hand deformity and other health complications.
Elsewhere, Ted is grappling with the loss of his father. Haunted by the persistent issues at the Rhodes & Miller site, he decides to act covertly, slipping Pat's contract documents to council member Sam Hagen. Confronting Roy, the council leader, Sam denounces the rigged tender contract, presenting irrefutable evidence that Pat had been improperly awarded the project. Roy promises to investigate, but Sam makes it clear that the documents he holds are mere copies, hinting at more where they came from.
While Connor undergoes surgery, we learn that Tracey is expecting twins, yet her joy is tinged with terror. Their paths cross again outside the hospital, where they share their updated plights. Susan mentions the journalist to Tracey, who expresses keen interest in speaking with him. Moved by Tracey's enthusiasm, Susan reconnects with Graham Hind.
Later that evening, Sam catches Ted in the act of depositing another stack of photocopies at his doorstep. Ted, desperate for change, urges Sam to take decisive action, painting a grim picture of escalating problems. However, Sam hesitates, acknowledging that confronting a beloved council figure like Roy could jeopardize his own political standing. Undeterred, Ted insists that doing the right thing trumps personal ambition.
The following day, Roy embarked on negotiations with Sam, only to descend into aggression midway through. Faced with this confrontation, Sam made the difficult decision to resign. Their discourse revealed Roy's ambitious plan to contest the upcoming elections and secure his reelection. Desperate for public favor, he insisted on Expediting the redevelopment project, regardless of the potential repercussions.
Meanwhile, Susan found herself entangled in a physical altercation with a fellow townswoman who had mocked her after her story hit the newspapers. Undeterred by her husband Derek's skepticism about the town's toxicity being linked to their child's defect, Maggie, Derek's wife, resolved to meet with Susan. Elsewhere, Tracey delivered her twins safely, bringing joy to all around her.
The day after, Susan sought Tracey's counsel at the park, inquiring about the feasibility of turning their plight into a legal battle. Tracey, ever supportive, guided her through the initial steps. Shortly thereafter, a lawyer, who happened to be the son of Susan's high school teacher, paid her a visit. He was keenly aware of the struggles the town's mothers faced and was eager to help.
Elsewhere, Ted found himself terminated from his council job, a retaliatory action for his relentless expose of the mismanagement of toxic waste and other irregularities tied to contractors approved by Roy. Concurrently, Sam presented the gathered evidence to the police.
That very night, Susan hosted a gathering at her friend Pattie's local bar, inviting the affected mothers along with their lawyer, Des Collins. Though she feared a lackluster turnout, she was pleasantly surprised when a multitude of families arrived in solidarity. However, the episode culminated in a shocking twist—the evidence against the council was deliberately set aflame, reducing their negligence to ashes.
