Although it is fun to see Vincent Price early in his career before his spine-chilling horror roles really took off, this psychological thriller feels long at 70 minutes.
Janet Stewart (Anabel Shaw) checks into a hotel at night and waits for the return of her GI husband. While in her room she sees a woman being murdered and sinks into a state of comatose shock. She's carted off to a psychiatric hospital but the psychiatrist (Price) is not all he seems.
A formulaic story isn't helped by the wooden performances of Shaw, of Lynn Bari as nurse Elaine Jordan, and by Frank Latimore as Lt Stewart.
Moody B picture visuals and the usual tinny music give this minor film a sense of space and time but overall 'Shock' is a bore which outstays its welcome.
Of interest to Price fans but not really much there for anyone else.
