'Psych: 9'

Is a hospital actively contributing to a wave of murders? That's the fear of an employee (Sara Foster, "The Big Bounce") whose own instability leads others to question whether her concerns are valid in this thriller.

The fact that she works the night shift sets up many of the attempted shocks here. Cary Elwes ("Saw") and Michael Biehn ("The Terminator") also star. DVD extras: deleted scenes; outtakes; production diary. ** (R: AS, P, V) (Also on Blu-ray)
