Tina is desperate to get her first kiss at her 13th birthday party. But after Louise breaks the deep fryer, Bob is forced to takes a second job as a late-night cab driver to pay for Tina's party. The situation worsens when the parents of Tina's crush refuse to let their son attend the party, and Bob has to do everything in his power to save his daughter's big day.
When Bob is invited to be a private chef on a docked cruise ship, he brings the family along to witness his skills outside of the restaurant. However, Bob's big day goes awry when the ship departs with the Belchers on board, and there is no one tending to the restaurant.
Bob, Linda and the kids go on a camping adventure and face the perils of nature... and Bob's intestines. Braving wild river rapids, eager squirrels and parent/child separation, the Belchers prove they are worth their mettle.
