When The Velvet Miasma self-destructed on stage in the mid
seventies, band members vowed they'd never perform
together again. But retro is in, and a promoter smells big
bucks in a reunion. Thor, the band's egocentric leader,
recruits aging hippie Paladin to dry out the lead guitar
player and try to persuade Maggie Thunder, the band's sexy
singer, to join
the tour. Meanwhile, Paladin's son, Eugene, replaces a
keyboard player blown up on a Mexican drug boat. It's the
kid's big break, until Thor moves in on his girl.
Paladin discovers why Maggie, now a strait-laced matron,
left the band. He promises to keep the dirty secret, but
all bets are off when Maggie's daughter auditions, Thor is
found beaten to death with an electric guitar, and Eugene
becomes a prime suspect.
With the help of Scan Man, Socks, and a cross-dressing
plumber, Paladin and his zoned-out friends muddle their
way toward truth, justice, and a killer who gives new
meaning to the term "off the charts."
