chunk: Banzai (Peter Weller) prepares to test his Jet Car, a modified Ford F-350 pickup truck powered by a jet engine and capable of exceeding the speed of sound. The car is also equipped with a secret device called an "oscillation overthruster", which Banzai and his associates hope will allow it to drive through solid matter. The test is a success: Banzai stuns onlookers by driving the Jet Car directly through a mountain. Emerging on the other side, Banzai finds that an alien organism has attached itself to the undercarriage.
  Hearing of Banzai's success, physicist Dr. Emilio Lizardo (John Lithgow) breaks out of the Trenton Home for the Criminally Insane, after being held there for 50 years. A flashback shows Banzai's mentor, Dr. Hikita (Robert Ito), was present at Lizardo's failed overthruster experiment in 1938. Crashing half through the target wall, Lizardo had been briefly trapped in the 8th dimension where his mind was taken over by Lord John Whorfin.
