Meet Sam, a bright student with a bright future. And everything is going her way. Until she turns 18. On her birthday, Sam discovers that her parents are actually well-known intergalatic thieves, and, much to her dismay, she's zipped away from planet Earth to escape some mean galatic lawmen who want to blow things up... literally!

To save the Earth, Sam must find the Evolutionary Cube, but unfortunately, Mom and Dad are no help. So living up to her "take-charge" personality, Sam does what any 18 year old would do - she joins up with some pretty shady characters and goes off on her own journey to find the Cube to save her world.
