Stewart is academically brilliant but socially clueless. Ashley is the
undisputed "It" girl in her class, but her grades stink. Their worlds
are about to collide when Stewart and his dad move in with Ashley and
her mom. Stewart is trying to be 89.9 percent happy about it, but
Ashley is 110 percent horrified. She already has to hide the real
reason her dad moved out; "Spewart" could further threaten her
position at the top of the social ladder. They are complete opposites.
And yet, they have one thing in common: they like everyone else
are made of molecules.
