Hoodlums steal a worthless painting, and Kent Murdock wants to know why. A collection of valuable Italian paintings finds its way to Boston, placed in the care of Professor Andrade. Before passing them to a museum, the professor hires newspaper photographer Kent Murdock to document them. On his way to the assignment, Murdock is stopped by a gunman named Erloff, who steals the reporter's identification — and pays his own visit to the professor.
But Erloff is not after the expensive stuff. He cracks Andrade on the skull and leaves with nothing but a worthless painting of a green-hued Venus. Murdock is perplexed. Why all the trouble for an ugly piece of modern art? But the jade Venus holds a terrible secret — and blood will flow before it comes to light.
