When
Francine becomes frustrated that the family is falling apart,
Stan suggests a vacation. The Smiths have a great time in
Maui until Francine,
Steve and
Hayley wake up to find themselves floating in
virtual reality chambers filled with a green, gooey substance. They learn that Stan programs a vacation in the goo chambers every year to escape the family. Haley and Steve, agreeing with their father, both attempt to use the chambers for themselves. Fed up with the family's fracture, Francine breaks down and gives up. Filled with guilt, the family decides to book a real vacation on a cruise, to which she eventually agrees. Meanwhile,
Roger, who wants to become a famous movie star, lands a part, only to quit when he is unable to cry on cue. He becomes a
Myra Hindley impersonator on the same cruise the Smiths are on. When Francine sees everyone acting uncharacteristically enthusiastic, as well as noticing Becky, the attractive event planner, hitting on Steve, she angrily believes she is in the goo chambers again and jumps overboard, expecting to wake up at home. The others, plus Becky, follow her into the sea and rescue her, but realize nobody told the ship to return for them. They
land on an island, where they learn that hunters living on the island plan to
hunt them down for sport, causing them to take refuge in a cave. The ship stops in
Cuba, where Roger is forced off. He resorts to becoming an
exotic dancer at a nearby
strip club, but his job nearly becomes
prostitution. Distraught by what he's doing, Roger breaks down in tears, to which a heartfelt
john gives him money and helps him escape. Back on the island, Beck is crushed to death during a cave-in, driving the Smiths to reluctantly
eat her to survive. The hunters then find them, and the family learns that the island—and the hunt—was part of the cruise. Reeling over the fact the ate Becky for nothing, Stan quickly asks where the family wants to go next year. The Smiths then happily float in a
hot-air balloon over a vast canyon, holding a toast "to the goo", revealing the family using the goo chambers together. ==Reception==
