A skip tracer--someone who collects late payments from people who've purchased appliances, etc., or takes them back them when they don't pay--repossesses a small radio from a deadbeat who's skipped payments. What he doesn't know is that a gang that has stolen diamonds from a Hollywood movie star has stashed them inside the radio, and they start hunting for him.

Director Lewis D. Collins' 1936 whodunit is about the investigation into the death of an elderly tycoon, who is murdered shortly after announcing he plans to change his will and give away his fortune.
