Driven

Lobster fisherman Karl Dengler is inhabited by the demon Krogan, and partners with other demon-possessed people to commit horrific acts of violence. When Krogan destroys the New York Aquarium's tanks of whales and dolphins, Det. Gavin Pierce's grandfather is one of the spectators killed. In his quest for vengeance, Gavin joins forces with Amy Kirsch, a sassy, drop-dead gorgeous computer hacker who has a homespun "fortune cookie" saying for almost every occasion. Recovering alcoholic Karianne Stordal suffers from her own demon and is commandeered by Krogan to help him commit vehicular homicide. Under hypnosis, she provides clues that help unlock the murders. As Krogan continues his reign of terror, Gavin and Amy turn to a reluctant exorcist-turned-dairy farmer who has been victimized by Krogan in the past.
