High Wall

Steven Kenet (Robert Taylor) says he killed his wife, but even he doesn't really know. A wartime head trauma has left him subject to disorientations and blackouts. So Kenet enters a psych ward where, the DA asserts, he'll hide behind the wall of an insanity plea.
But truth cannot hide. And Kenet - assisted by a ward doctor (Audrey Totter) - is driven to find that truth. (official distributor synopsis)
