Hanging out along the creekside, Truly and the Boys spot a bottle with a note in it floating down the river so of course Alvin & Billie have to try to get the bottle. A stranger is looking for Clegg - a phone call from Pearl sends Clegg into a worry.
Howard is on 24-hr "lock down" by Pearl, so his friends accept the challenge to help him escape. Barry thinks he's missing out on something because he feels contented with his life; Entwistle has too much fun with his dog.
Miss Davenport makes a pass at Barry and now he refuses to go back to the library; Pearl spots a personal ad in the paper and figures it's Howard setting up a meeting with Marina; Alvin decides to make Nora jealous.
