Synopsis:
A woman is murdered in the flower shop of Dinah Drake. The murderers belong to a cult and abduct Larry Lance. Black Canary recovers a glowing crystal that the killers had sought. She offers to trade it back to them in exchange for Larry. However, her plan fails, and she is captured.

Larry and Black Canary are prepared as sacrifices by the cult leader. Black Canary escapes and exposes the swami leader as racketeer Bullet Benn. Then she shows the other cult members that the crystal was a fake. The racketeers fooled the members in order to steal money from them.
