John Rambo is released from prison by the government for a top-secret covert mission to the last place on Earth he'd want to return - the jungles of Vietnam.

A new high tech laser is being developed under the watchful eye of a Scientist when a mercenary group tries to steal it. It is up to the Night raider to return the laser safely before it falls into the wrong hands.

A Japanese policeman in Los Angeles uses an ancient magic sword to battle killers and an extortion ring.

The plot concentrates around John (Bruce Ly), a policeman who reforms violent police officers by teaching them martial arts, and a trigger happy cop, Houston, played by Majors. Predictably enough, the two are paired together and they set out to find the person responsible for selling cyanide laced cocaine.
