The titular Mindhunters are a group of young FBI students who are undergoing training as profilers . Their instructor, experienced profiler Jake Harris ( Val Kilmer ), employs a highly realistic training approach by assigning the group variants of real investigations, including elaborate sets, props, and FBI actors to play out each scenario .
The students include Bobby ( Eion Bailey ), a young man with a talent for fixing things; Vince ( Clifton Collins Jr. ), a wheelchair-using ex-cop who goes nowhere without his gun; Nicole ( Patricia Velásquez ), a smoker who is attempting to quit; Sara ( Kathryn Morris ), a talented but insecure profiler who is terrified of drowning; Rafe ( Will Kemp ), a very intelligent, caffeine-powered British investigator, Lucas ( Jonny Lee Miller ), a supposedly fearless man whose parents were killed when he was a child; and J.D. ( Christian Slater ), their leader and Nicole's lover. Nearing the end of their training, the group's over-all morale is high, though Vince discovers that neither he, nor Sara, will make the rank of "Profiler" after secretly reading their training evaluations.
The group travels with their instructor to a small island off the coast of North Carolina to complete their final training exercise. At the last minute, they are joined by Gabe ( LL Cool J , listed as James Todd Smith), an outside observer who has requested to see Harris' teaching methods in action. The island, used by the Navy to train for hostage rescue and outbreak scenarios, has an existing "population" of target dummies, vehicles on mechanical rails, and small town storefronts. Similar to their earlier training scenarios, Harris plans on using the town for their final exam, tracking a serial killer calling himself, "the puppeteer." The team settles down for the evening and practice their profiling skills on each other and Gabe, who reveals that he is also a skilled profiler in his own right. Sara and Lucas briefly bond over losses in their families; Sara reveals that her sister was murdered and drowned, creating her persistent fear of water, while Lucas shares that his parents died when he was 10. The two resolve to use the scenario to confront their personal fears.
The following morning, during the initial investigation of the "puppeteer" scenario, J.D. dies after triggering a clock mechanism that causes a tank of liquid nitrogen to freeze him instantly. Convinced that J.D.'s death is neither accidental, nor part of the training simulation, the group heads to the dock to leave the island; but the boat explodes. After returning to base, the group realizes that broken watches and clocks found at each scene point to the fact that there is a real serial killer on the island, who has co-opted the training exercise and is now hunting them down. The killer's M.O. indicates that he or she plans to kill someone at a time designated by the broken clocks. After a thorough search of the island reveals no other personnel, the group concludes that the killer is one of them.
At first, suspicions seem to point to Gabe, as Lucas found maps and documents of the island; however, before the group finishes confronting him, they each pass out, realizing that their coffee was drugged. They awaken to discover that the killer murdered Rafe while they were unconscious, and suspicions again return to Gabe. He temporarily deflects these suspicions when he saves Vince from another trap involving broken water pipes and lights electrocuting the water. However, Bobby is killed by a secondary trap when he goes to turn off the water. Sara, meanwhile, deduces that the traps are based on their strengths, talents, and weaknesses; and the remaining profilers elect to stick together, to keep an eye on each other. After more clues are discovered, suspicion shifts to Sara, who insists that she's being framed. Nicole, suspicious that the killer is among the group, leaves to be alone; but she becomes the next to die after she smokes a cigarette laced with acid.
Unexpectedly, the island's speakers begin to broadcast a taunting message from Harris, making them realize that he did not leave the island, though he led the profilers to believe that he had; convinced that Harris has been the killer all along, the remaining profilers search for him. Vince refuses to join the search party and stays behind at the lab. Sara, Gabe and Lucas find Harris and two other FBI agents next to him, all dead; Harris has been strung up to wires from the ceiling as a sort of marionette, just like the fake "puppeteer" crime scene that they were to investigate. The three turn on each other after triggering another trap, and Lucas is shot during the ensuing gun battle. Vince finds himself trapped in a freezer after he tries to reload his empty gun, but he escapes although he dies when his gun backfires on him in the elevator.
Sara finds Vince's body, but she is ambushed by Gabe, and the two struggle physically and mentally to profile the other, each believing the other person is the killer. Gabe manages to overpower Sara but is then attacked by Lucas, and the two of them get into a protracted fight. Sara eventually recovers and hits Gabe over the head with a fire extinguisher . Lucas reveals that he had been wearing a bullet-proof vest , allowing him to survive getting shot on the street. With Gabe subdued, he expresses doubt that there's enough evidence to prove that Gabe was the killer. Sara, however, reveals that she found a way to get one step ahead of the killer. Knowing that the killer was relying on timed mechanisms and remotes, as well as enjoying watching their anxiety under pressure, she changed one of the clocks to appear slow by fifteen minutes, and covered it in a powder that glows phosphorescently under blacklight . Reasoning that the killer would not be able to resist setting the clock to the correct time, she grabs a black light to scan Gabe's hands and reveal him as the killer. Sara instead finds the marking powder on Lucas' hands instead of Gabe's. Lucas confesses that his parents did not die in an accident, but that he killed them. Struggling ever since to find more thrilling targets to kill, he joined the FBI and planned to kill his brilliant fellow profilers, the only people he thought would be "worthy prey." Lucas tries to drown Sara, but she manages to kick him into the water. The two both manage to recover their weapons underwater, but Sara manages to shoot Lucas first.
Lucas recovers and begins to taunt her about the evidence he planted blaming her until Gabe reappears: he is the last witness. In a last desperate effort, Lucas attempts to regain his weapon, forcing Sara to kill him, shooting him through the top of the head as he bends down to retrieve his weapon. The following day, Gabe and Sara flag down the U.S Navy helicopter to leave the island, determining that they've sufficiently secured the scene.
