Tracker Season 3 Episode 3 Unravels a Chilling Cult Mystery on CBS

The CBS hit drama “Tracker” aired its third episode of Season 3 on November 2, 2025. Titled “First Fire,” the installment delivered a Halloween-themed mystery that plunged Colter Shaw into a dark investigation. The episode blended procedural crime with unsettling horror elements, marking a tonal shift for the series.

Colter Shaw, played by Justin Hartley, was hired to find an escaped psychiatric patient. The case quickly evolved into a disturbing hunt connected to a fanatical religious cult. This storyline represented one of the show’s most intense and eerie narratives to date.

A Halloween Escape Sparks a Sinister Hunt

The episode opened at a psychiatric hospital in Wyndam, Massachusetts. Patient Heston Koontz murdered a nurse and vanished during a Halloween night power outage. His history of arson made him an immediate danger to the community.

Colter Shaw was brought in by Heston’s worried parents, Lawrence and Molly. They feared their son was searching for a woman named Emily Collins. Colter partnered with local detective Dundee to track the escapee.

They discovered Heston did not act alone. An accomplice had used a stolen keycard to facilitate the breakout. This twist pointed to a larger, more organized threat lurking in the town’s shadows.

The Disturbing Link to a Religious Cult

The investigation led Colter to a Bible study leader, Bill Prugalidad. He was found dead, with a strange symbol left at the scene. The same symbol was discovered in Heston’s personal Bible.

This clue connected the case to the Sisters of the Sacred Fire convent. Colter and Dundee’s visit there revealed a splinter group called “Fideles.” This violent cult believed in purifying souls through fire.

According to industry reports analyzed by Reuters, narratives involving cults and institutional secrecy resonate strongly with modern audiences. The episode tapped into this by framing the convent as a front for fanaticism. The cult had abducted both Heston and Emily for a ritual burning.

A Fiery Confrontation and Emotional Aftermath

The climax featured a race against time to an abandoned homestead. The cult, led by Sister Carlotta, intended to burn Heston and Emily alive. Detective Dundee was injured trying to stop them.

Colter fought through flames to save Emily. In a tragic turn, Heston broke free and killed Sister Carlotta before dying from his injuries. The resolution was both action-packed and somber.

In a poignant final scene, Colter refused to accept his reward money. He insisted it go to Emily to help her rebuild her life. This act underscored his character’s moral core beyond his reward-seeking profession.

The third episode of Tracker Season 3 successfully fused horror and heart, proving the series can venture into darker genres while staying true to its emotional core. This chilling cult mystery expanded the show’s narrative boundaries and left fans eager for the next case.
