Tommy defends a group of local squatters against small-minded suburban prejudice. Neighbours Jonathan and Beverly are labeling the squatters as anti-social before they've even met them. The trouble is, Tommy hasn't actually met them either. After a visit to the squat he realises that sometimes small-minded prejudiced suburbanites can be right.

Tommy works at a nearby private boys' school, an institution he considers to be conformist and straight-laced. He gets invited to talk to the children about the pest control business. The kids appear more interested in his roadie work for the Floyd...and turn out to be more free-spirited than Tommy bargained for.

A courtroom drama unfolds as Tommy defends himself from the charge of fare evasion. Will the judge be swayed by Tommy's passionate defence?
