In this riveting film based on the popular 1980s series, Dr. David Banner (Bill Bixby) devotes his time to trying to fix the Gamma Ray Transponder so he can shed his powerful green-hued alter ego. But a corrupt ex-soldier wants to steal the machine for his own evil use. Meanwhile, Dr. Banner's old student Donald Blake claims he can summon the spirit of Thor because he's found the god's hammer.
