Bridget's delighted by the unexpected arrival of her older brother, James. He's on a mercy mission: their younger brother Ben has broken his ankle, and he needs Bridget to replace him in a skateboarding event being held just near Blue Water Beach. Eager to help her brothers win the race, Bridget tries to convince Bec and Garry that skateboarding is perfectly safe and that there's little risk of injury. James can see this strategy isn't working and secretly tells Bec and Garry that he's hatched a fake plot to get his whole family together for their mother's birthday. Meanwhile, Charley and Guy come home to find two of James's spare skateboards against the wall of the house. Assuming they've been left there for some 'dry land' practice, they take them out for a spin, with disastrous results. Out of control, they skate down the street and crash into a garage sale, creating havoc.
