Main Cast of Episode 18
The Core Team in Action

Justin Hartley as Colter Shaw
Justin Hartley leads as Colter Shaw, the expert tracker racing to find missing beauty queen Riley Adams.

She’s pivotal in connecting Riley’s case to broader stakes.
Abby McEnany as Velma Bruin
Abby McEnany portrays Velma Bruin, Colter’s handler who kicks off the episode by assigning the $15,000 reward case via a quick call. ScreenRant (Apr 28, 2025) critiques her brief “two-liner” scene, but McEnany (Work in Progress) adds warmth. X posts, like @CBSDramaFan, wish for more Velma: “Give Abby McEnany more screen time!” (@CBSDramaFan, Apr 2025). Her role is small but sets the plot in motion.
Eric Graise as Bobby Exley
Eric Graise is Bobby Exley, the tech guru aiding Colter remotely. In “Collision,” Bobby teams up with new member Randy to track Riley’s digital trail, per TV Fanatic (Apr 28, 2025).

Guest Cast of Episode 18
Bringing Riley’s Story to Life
“Collision,” directed by Joel Novoa and written by Dominique Holmes and Ryan O’Nan, follows Colter’s search for Riley Adams, a former model hiding a pregnancy secret (Tracker Wiki, Mar 10, 2025). The guest cast adds depth to this twist-filled case.
Annalisa Cochrane as Riley Adams
Annalisa Cochrane stars as Riley Adams, the missing 26-year-old ex-pageant queen and model. Collider (Apr 28, 2025) highlights her pivotal role, with Riley’s car crash and pregnancy driving the plot.

Her secret shapes the episode’s shocking reveals.
Summer Lynn Gillespie as Cheryl

Additional Guest Stars
- Lisa Eichhorn as Susanna Adams: Riley’s worried mother who hires Colter, offering a $15,000 reward. IMDb (Apr 27, 2025) lists Eichhorn (The Talented Mr. Ripley), but some X users, like @Viewer123, criticized her as “overacting” (@Viewer123, Apr 2025).

Why the Cast Shines
A Mix of Grit and Emotion
The ensemble balances Tracker’s action and heart. Hartley’s Colter anchors the case with rugged charm, while Rene and Graise add humor and tech savvy. Guest stars like Cochrane and Gillespie elevate the “Lifetime movie” trope with emotional depth, though CBR (Apr 29, 2025) notes the plot leans on clichés (CBR, Apr 29, 2025). X’s @SeriesBinger said, “Collision’s cast made a predictable story gripping!” (@SeriesBinger, Apr 2025). The episode’s 8.0/10 IMDb rating reflects strong performances despite mixed writing reviews (IMDb, Apr 27, 2025).
