Steve and pals undertake a cross-country road trip to attend the funeral of Snot's father, and at the same time get their friend to confront his emotions over the old man's death. But Steve's commitment to Snot takes a backseat when he falls for a young lady along the way. Back at home, Stan and Roger invent an automatic cake-cutter and market it on a home-shopping network, but the partnership is tested when the two have a problem agreeing on how to slice up the profits.
