When twin sisters Ana and Tara Spark run away from their coldhearted stepdad, they are determined to return to the only place they ever felt at home. The only problem is...that place is in Montana, they are in California, and their means of transportation consist of their own feet and a couple spunky mustang mixes. Best friends Marty and Eugene refuse to be separated, even if they have no idea where to go in their rickety Volkswagen Beetle once their loveless foster home is left in the dust of its barely attached wheels. Gamma and Nana were neighbors for years. Now they are restless roommates unsure of their ages but sure they are too young to be cooped up in a nursing home. What do you get when the escape paths of these mismatched runaways unexpectedly collide along the same stretch of railroad tracks? The answer is more adventure than any of them bargained for.
