Mississippi Beaumont is in a family full of talented people. Each member of her family has a special talent that they inherit on thier 13th birthday. Take her brother Rocket, for example. He can shoot powerful bursts of electricity whenever, wherever. Mibs does not have anything special happen on her 13 birthday. When Mibs finds out that her father is injured, and only her big brother Rocket and her mom can go to see her dad in the hospital, Mibs isn't exactly happy. So she and her other brother, Samson sneak aboard a big pink bus, hoping that the bus is going towards the hospital. But the bus is not going the right way. The driver does not know that they are there, and if he finds out, the kids will be in big trouble.
