Luanne and Bobby each face a crisis: she's fearful of failing her beauty exam, while he frets over his first boy-girl party.

When Luanne's mother, Leanne, is released from prison, she starts living in the Hills' garage, and becomes romantically involved with Bill. Bill is busy fighting a foot fungus, with every last dime.

When Mega Lo Mart starts selling propane, Strickland Propane can't compete with their prices, and Hank loses his job. He winds up working in the propane department at Mega Lo Mart, under the supervision of Luanne's boyfriend Buckley. Hank and other Mega Lo Mart employees decide to protest the way the company destroys small businesses, by disrupting a concert by the company spokesman, Chuck Mangione. Meanwhile, Luanne, who wanted Buckley to give her the job that he gave to Hank, tells Buckley she's breaking up with him. And Hank, Luanne and Buckley are the only people in the Mega Lo Mart when Hank notices a leak...

While studying for her beauty school exam, Luanne sees someone bouncing on Buckley's old trampoline. It's Buckley, who has come back as an angel. Hank and Peggy think Luanne was hallucinating after using too many hair-dying chemicals, but Hank's friends come to believe in the existence of Buckley's Angel. But Luanne finds that Buckley isn't much more help to her as an angel than he was when he was alive.
