When the family can’t agree on where to go for their dream vacation, they enter a competition as two different teams, boys vs. girls, with the winners getting to decide.
After their first year living with norms in Hiddenville, the Thundermans are in need of a vacation. Max and Phoebe reveal that their school is hosting a family competition in which the winning family gets a chance to go on their dream vacation.
Unfortunately, the family can't agree on where to go for their dream-vacation. Phoebe wants to go to a castle while Max wants to go to the beach. So, they hold a family vote to see who wants to go to the beach and who wants the castle. Phoebe, Barb and Nora vote for the castle. Hank and Max choose the beach. Billy is undecided but since is easily convinced by the boys to join the boys side. Needless to say, it becomes a boys vs girls competition. The only resolution is to compete against each other and the winning team gets to decide.
The competitions begin. Max uses his powers and Phoebe calls him out for cheating but Hank says that the goal is to win by any means necessarily. So, it turns into a super-powered competition. When Phoebe almost gets hurt, she takes advantage of that and fakes serious injury. Hank goes to check on her, but Phoebe steals the ball from Hank, and the girls win. Max calls out Phoebe for lying but Phoebe reminds him that they're to win by any means necessary. After losing the game, the boys say that they will not join the girls at the gaming competitions at school.
On the game day, Phoebe, Nora and Barb go to register, but they're told that The Thundermans have already registered. It turns out Max and Hank went early to register. Max had also registered Phoebe's team as the second placements. Principal Bradford is in charge of the competitions and complains about how he has nothing else to do or family or friends. The two Thundermans team express a lot of rivalry during the games but at the end of the day, both teams make it for the finals the following day.
Back at home that evening, the tension between the Thundermans boys and girls intensifies(mainly Max and Hank vs Phoebe and Barb). They refuse to share table, food or anything. This hurts Billy and Nora because they always eat together and play together. Billy talks Hank and Max into being nice to the rest of the family. Nora talks to Barb and Phoebe about it as well. So, Phoebe and Barb agree to let the boys win the following day.
During the finals, the girls team works hard to lose to the boys team during the obstacle course but it becomes almost impossible because the boys team is also trying to lose to the girls team as well. At the end, they realize that caring about family is more important than winning the stupid competition. So, they work together to win as a family to defeat the Petersons family that was getting so close to them.
At the finish line, Nora's Bow falls off ahead of the line. So, the Thundermans win. They agree to decide rationally where to go, but Nora says that her bow one, so she gets to decide. They go to the castle.
Realizing that the Petersons are really close behind them, Hank throws Max across the finish line, and the family wins. They try to decide rationally, but Max says that he probably broke a rib by falling across the finish line. They go to a beach.
