Mindhunters

“For seven elite profilers, finding a serial killer is a process of elimination. Their own.”

A group of FBI trainees is sent to a remote island for a final profiling exercise, and partway through they realize one of them is a killer. Renny Harlin pairs Sara Moore (Kathryn Morris) and Lucas Harper (Jonny Lee Miller) with the rest of the class, each of them trained to read the people around them. Sara has to work out whom to trust, and the answer keeps coming back to the classmates she's sharing a locked building with.
