This film is a class "A" drive-in special. The action is stiff and the continuity is not. The murder in the tunnel of love is totally silly. The girl turns toward her killer exposing her chest to his attack. Her head falls back dead and then the next scene her head is back up. The dagger is obviously pointing down into her blouse and you can see the blood pouch through the fabric before the killer pulls it out. Then she falls dead over the side of the boat and when seen from afar she has moved upward twice in the next scene. What a mess for the continuity person. Otherwise, the film is good for a few laughs on a lonely night.If you have had a few to drink.
