He is a lingerie salesman who, because he is such a softie, has no success at all with the ladies who don't like him at all but who all fall for the bad gangster types.
By accident, one of the gangsters is killed by a competitor and his body is dumped in his apartment.
Now everyone thinks that the seller is a new crime boss and he is assisted by his lawyer friend who has never won a case.
One thing is certain: beautiful women fall for the wrong types, it is exaggerated here, but there is some truth in it.
Furthermore, it is an amusing comedy with a nicely playing Stuart Erwin and a stunning lady Anne Gwynne who at first doesn't want to know anything about him but (unbelievably) still falls for him at the moment supreme (oh well, there has to be a happy ending, right? ) .
