Aging Miss Lowen (Squire) has an attractive adopted daughter who's made a romantic "pen pal" out of a guy who turns out to be a convict (Gulager) at a near-by prison. Trouble is he has escaped and the daughter has gone visiting, so the vulnerable Miss Lowen is now alone with an amorous convict on the loose.
Though there is some suspense, much is removed by the fact that we know Rod, the convict, doesn't want to hurt the older lady. So we're left wondering how the predicament will resolve itself. Then too, the action of the cops to leave Lowen alone in the house seems highly illogical. It's actually pretty slender fare, not up to usual Hitchcock norm, with an expected twist you may see coming. It's also among the most cheaply produced—a single parlor room set and three actors. Gulager does a good job impersonating a desperate con, but otherwise it's a highly forgettable episode.
