ICU nurse Max Mason fears his pregnant wife is the latest victim of a serial killer who has terrorized their small New Hampshire town. The investigation is at a standstill as the prime suspect, Lincoln Raider, is in a coma. In a desperate and unethical act, Max sits at Lincoln's beside night after night employing brainwashing techniques and subliminal suggestion to convince the suspect they are kindred-spirits, hoping it will lead to a confession or at least a clue. When Lincoln awakens he draws Max into a whirlpool of terror, deception, and violence, ultimately pulling Lincoln's wife and daughter into the vortex as well.
