Physics 101 Much? is episode 1 of Season 3.
The spies are sent to investigate several mysterious thefts of high-tech gadgetry. What they discover is a villain who can create a force field that cancels the effects of gravity. With plans to use his device on a much larger scale, can the spies stop him before it's too late?
In the B-story, the girls' parents are letting them live together in a new Beach House while they are vacationing in Europe, and then they compete over who gets the best bedroom (which Clover gets in the end).
