Short-lived spinoff to "Head of the Class". Billy MacGregor, the wacky Scot who took over the IHP class after Mr. Moore left, has moved on now that Filmore High is rubble. He has decided to move to California (with his plant, Ringo). In order to avoid being deported, Billy marries a working mother with kids. There is one condition though: No romance, no sex, and no affection of any kind. Despite that, Billy's charms win her kids over.
