Batman detects an coded infra-red signal being transmitted from a lighthouse that calls for the death of Robin. Batman orders Robin to return to the Batcave where he will be safe. He then investigates the lighthouse of Cyrus Spume. He spots the crooks plotting to kill Robin, but he wants to find their leader.

Batman arranges for Robin to appear to die by killing him himself. The crooks then proceed with a diamond robbery. Batman tries to stop them, but he is caught. Robin is still alive and comes to his aid. Together they take down the crooks including Cyrus Spume who is the gang boss.
