Synopsis:
A radio station holds a contest, giving listeners a chance to guess the identity of Mr. Mystery. The mystery man is really Robin. When he is trying to apprehend a gang of crooks, one of them recognizes his voice from the program. He then captures Robin, hoping that the station will be unable to have the mystery guest appear. Then the crook can correctly guess that Robin is Mr. Mystery and win the prize.

Robin outwits the crook by appearing on the program, despite being tied up in the crooks' hide-out. He broadcasts his voice via a hidden microphone. The gang is fooled, and Robin is able to get away. After capturing the crooks, Robin returns to the radio show where his identity is correctly guessed by another listener.
