Both somewhat dull and weirdly fascinating, the flick starts with a long voiceover and lengthier flashback to explain how two army buddies, later roommates, (one incapacitated by PTSD, the other attending night school to better himself) get mixed up with a pair of twin sisters of opposite character (Bonita Granville). When one of them suddenly disappears, the investigation begins. Don Castle plays the straight upstanding veteran beside Wally Cassell's nervous wreck, and the two find ways to ward off a cloud of suspicion over their possible involvement in the disappearance. This is a rough-and-ready B movie but all the more authentic for that. Shot entirely in the gloom of night, it's dreary, rain-soaked and confined to about three locations - but the strange relationship between the ex-soldiers and the twins keeps one engaged, as does the whodunnit aspect, which turns out to be overly convoluted. A palpable sense of ennui, existential angst and cynicism runs through the film which, with some excellent use of shadow and light, elevate this low-budget Monogram movie into something very watchable. There's plenty to like here.
