Ninja Connection (1986)

When authorities need a go-to guy to stop an international drug-smuggling ring from committing an act of terrorism, a dauntless American spy volunteers for the job. Going to Thailand on a do-or-die mission to checkmate the drug lord and his ninja minions, however, proves a more complicated task than expected. But clinging to the code of the venerable shadow warriors gives him the courage to bring the baddies to justice.
