Synopsis:
Roy Raymond interviews several applicants to appear on his show "Impossible -- But True." One of the applicants, Mighty Maro, claims to read minds. He successfully reads Roy's mind, then appears as a guest on the show.

Crooks watch the show, then recruit Maro to work in their gang. Maro is able to gain secret information by reading minds to help the crooks in their robberies. The gang leader comes out of hiding to help with the theft of a rare jade eye. While committing the robbery, Maro springs a trap on the crooks, revealing himself to be an undercover officer. Roy was in on the scheme to trap the gang leader and helped fake Maro's mind reading power.
