The two attackers were brothers, and Conroy, the brother who survives, vows to avenge his sibling's death.

He is still recuperating from the mugging when his newborn child is kidnapped from the hospital. Struggling with his own emotional turmoil and his wife's devastated reaction to the kidnapping, Marin must race against time to stop a deranged stalker from carrying out an act of deadly revenge.
