Nichols (Jeff Goldblum) and Stevens (Saffron Burrows) are called to investigate after happily married couple Linda (Nadia Bowers) and Ted (Derek Cecil) are assaulted and sedated by a masked assailant while leaving the marina. Ted later emerges in a forest, confused and traumatized. Park workers discover him, and he says that he may have just killed his wife. Upon further examination, Linda's body reveals traces of an adhesive and suction cup marks. Captain
Callas (Mary Elizabeth Mastrantonio) recalls that there have been four similar killings around the country in recent years. As Detectives Nichols and Stevens pursue the case, they discover that motive can sometimes be harder to ascertain than the killer's identity.
