The evil scientist Dr. Caronte plots to revive the brains of three dead scientists and use them to obtain the formula for the super-powerful neutron bomb. The resulting creation needs blood lots of blood, sending Caronte's midget assistant Nick and his legion of mutant monsters out to get fresh victims. However, the masked atom-superman Neutron vows to put a stop to Caronte's deeds.

Jake Remy leads a gang of outlaw cutthroats making their escape toward Mexico from a successful robbery. Barring their way is a river--crossable only by means of a ferry barge. The barge operator, Travis, refuses to be bullied into providing transport for the gang and escapes across river with most of the local populace--leaving Remy and his gang behind, desperately seeking a way across. A river-wide stand-off begins between the gang and the townspeople, both groups of which have left people on the wrong side of the river.
