In England Miller has stolen the famous Stanhope diamonds, he takes them over to New York on an ocean liner where he plans to sell them. His partner in crime Waite (Ray Collins) double-crosses Miller and kills him, aided by the valet Dodge (Walter Kingsford). Waite then assumes Miller's identity. However, there is a woman (Betty Pierce) aboard the liner who has a grudge against Miller...
When a body is found aboard the liner in Miller's cabin, Inspector Carr (John Hamliton) and his friend Dr Crabtree (Donald Meeks) come aboard. The body is found to be neither Miller or Waite! A baffling mystery therefore, though Dr Crabtree soon unearths some clues...
There is a lot of storyline here packed into just over twenty minutes, which is all the more impressive when you consider the rather slow and ponderous pace of the film. Unfortunately due to the short length it can be confusing at times. It is a decent enough mystery though could have been a lot better.
