An enjoyable early talkie crime melodrama. Eighteen months before slimy businessman Frank (Rod la Rocque) is taking his slightly naive secretary Ann (Barbara Stanwyck) on a rum boat. He plies her with booze and tries to have his wicked way with her, but her honour is saved by a police raid...
Now Ann is happily married to Lawrence (William Stage Boyd) and living with him and his young sister Helen (Betty Bronson). To Ann's shock Helen has a new boyfriend... Frank! Lawrence finds out Frank has broken up his friend's marriage with his womanising ways and goes to have it out with the cad. A struggle ensues and Frank lies dead. Lawrence flees and locks the room... a complication being Ann was already hiding in the apartment having arrived earlier to have it out with Frank herself...
A simple enough plot but enjoyably done. The final act with the police investigation by the DA (Harry Mestayer) is quite exciting with a couple of plot twists. An early talkie which avoids some of the flaws of the period though is fairly static, you wouldn't be surprised to find out this was adapted from a stage play. Literally a locked door murder mystery and fine for that.
