After their parents divorce, 12-year-old Josh and 7-year-old Sam decide to go on an underage road trip. Sick of being ferried between their distant mother and remarried father, Josh and his brother steal a car and set out for Canada. The runaways' journey gets more interesting when they pick up a drifter named Alison (Martha Plimpton). More bizarre yet, Josh has convinced his little brother that he's a "Strategically Altered Mutant."
