The whole family gets stuck together in a snowy mountain cabin and the guys find a pregnancy test, but they don't know if it belongs to Crystal or Oliver's new girlfriend (who has slept with Oliver and Ben).

Stewart ends up in the ER with a backache on, of all days, Valentine's Day. Ben somehow gets locked in Crystal's bathroom while she is taking a bath, and Oliver tries his best to get out of a Valentine's dinner with his mother.
