The members of Led Zeppelin are called back from vacation by manager Peter
Grant to play Madison Square Garden. The film is enhanced by each of the band
member's personal fantasies (hallucinations?), such as the opening scene (which
is awfully confusing the first time around) in which Peter Grant, dressed in a
1930s black gangster suit drives a 1930s black Ford to a house and blasts
everyone with a machine gun.
