Boston Blackie (Raymond Glenn) has just spent two years in jail, He makes a vow to go straight but ends up involved with Sylvia (Corliss Palmer) who has stolen a necklace from a dancer.
It turns out the jewels belong to Sylvia's father (who was having a bit on the side with the dancer). Blackie agrees to break into the father's safe to put the jewel's back.
The star of the film though is Blackie's dog Strongheart who gets top billing! The film is fine enough, nothing at all like the later talkies. A pleasant if not exceptional watch.
