Bad Samaritan

A wealthy serial killer (David Tennant) holds a woman captive in his cabin after she's discovered by a parking valet (Robert Sheehan), who notifies the police but becomes Cale's target as he tries to silence him. As Sean Falco navigates this cat-and-mouse game, Cale escalates his attacks on those around him, including Sean's girlfriend and his family. Sean ultimately outsmarts Cale and rescues the captive woman, Katie.
