In a thrilling departure from his usual cases, Colter finds himself in St..
Louis on a mission unlike any other in "St. Louis," the fifth episode of
Tracker's first season. Hired by a teenager, Stephanie Porter, Colter is tasked
with locating a missing witness who could exonerate her father, Clay, from a
murder conviction.
The case takes a personal turn for Colter, with the odds stacked against Clay's innocence. Even Reenie, Colter's trusted legal expert, initially doubts Clay's story. However, Stephanie's unwavering faith and an anonymous tip propel Colter forward.

Colter delves into Clay's past, uncovering a tense relationship with his deceased business partner, Avery. Clay insists on his innocence, claiming he left Avery alive after a heated argument. Meanwhile, following the anonymous tip, Teddi and Velma lead Colter to a clandestine poker game, hoping to find the mystery witness.
The high-stakes game takes a dramatic turn when the authorities raid the establishment, arresting everyone. Undeterred, Colter identifies a woman who seems shaken by his inquiries. This woman, the true mystery witness, reveals Mallory, Avery's girlfriend, witnessed the murder. Fearing for her life, Mallory went into hiding.
The investigation takes a dark turn when Clay is attacked in prison, seemingly due to Colter's digging. Clay's public defender proves unhelpful, displaying a lack of faith in his client and a surprising knowledge of the witness Mallory.
Colter tracks Mallory down in Kansas City, only to be ambushed by her and a mysterious figure, Uncle Max. Mallory reveals Cesar Ashford, not Clay, murdered Avery. With Cesar likely on his way to silence Mallory, Colter and Uncle Max devise a plan to protect her.
The situation escalates when Reenie discovers Clay's lawyer is working for Cesar. The corrupt lawyer kidnaps Reenie in exchange for Mallory. Colter, aware of the lawyer's phone tracking, devises a daring rescue plan.
A tense standoff ensues, with Colter using his resourcefulness to expose Cesar and the lawyer. The episode culminates in a heart-stopping chase and a final confrontation between Colter and Cesar. Justice prevails as Clay's conviction is overturned based on Mallory's testimony.
"St. Louis" showcases Colter's unwavering commitment to justice, even in the face of overwhelming odds. The episode masterfully blends action, suspense, and a touch of moral ambiguity, keeping viewers hooked until the very end. The personal aspect of the case adds depth to Colter's character, while the cliffhanger ending promises even more excitement in upcoming episodes.
