Seven from Heaven (1979)

In this action-packed drama, a beautiful singer decides to put her career on hold when her younger brother, who had a problem with drugs, is severely beaten by a gang of dope dealers. She assembles a group of seven beautiful crime fighters, and they hit the road in their customized van looking for an opportunity to break open the drug ring run by Farrell (Jack Palance) and Burke (Peter Lawford). The inarguably remarkable supporting cast includes Alan Hale Jr., Pat Buttram, Jim Backus, Neville Brand and Arthur Godfrey.
