Child psychologist Carter Nix is a loving and caring family man, but under this appearance lies a dark and troubled past. Grappling with the consequences of this past on his own psyche and the influence of his returning father and violent brother Cain, Carter becomes involved in a series of murders and kidnappings. Meanwhile, his wife Jenny rekindles an old love affair, placing herself in the crosshairs of her increasingly unstable husband.
