His stuntman Jimmy falls to his death after multiple sabotage, including the radio instructions.

Jesse also gets a small part and enjoys snooping, helped by a cute secretary. Then a locked door nearly kills Steve and Carl in a take of an explosion, and the one man who had opportunity for that once was injured because of Carl. Mark discovers on tapes a trampoline sabotage proving Jimmy as the intended victim of the fatal fall. Yet another actress s medical diagnosis leads to other suspects...
