Dr. Lila Coletti (Gina Gershon) is a psychiatrist to mentally disturbed prison inmates. She's also a recent divorcée, devastated after losing custody of her children. So when her ex-husband and his girlfriend are murdered, Coletti emerges as the prime suspect of the investigating officer, Det. Macy Kobacek (Michael Biehn). Coletti soon learns the killer is obsessed ex-con Ed Baikman (Sean Patrick Flanery), a former patient who threatens to incriminate Coletti unless she gives in to his demands.
