Teens run amok in this drive-in double bill from splatter master Herschell Gordon Lewis. In Just for the Hell of It, teenage gangs terrorize a town. When a good kid named Doug (Rodney Bedell) is threatened, gang leader Dexter (Ray Sager) stops the fight. But will Doug and his girl (Agi Gyenes) be spared the next time? In Blast-off Girls, up-and-coming rockers Big Blast need a boost, so their manager hires go-go-dancing back-up singers.
