The Black Cobra
In the black of night on a super highway, a truck carrying a sinister cargo of narcotics rushes on. Suddenly a white police car forces it to a stop. As the driver and his chief step out, they realize that they are at the mercy of a rival gang - and not the police. The syndicate chief vainly tries to escape and is murdered. To obliterate all traces of the crime, the gang sets the truck afire and drives it over a mountainside. In the confusion the driver escapes and seeks refuge with friends. The police find the burned truck and the driver becomes hunted on the suspicion of murder. The driver then forges a trail of vengeance on his sinister search to prove his innocence.
