It is almost Christmas when twelve-year-old Jimmy undertakes a project to find homes for stray animals, but it takes Lassie, helped by God, to make an animal lover out of a grouchy neighbor.
Jimmy and his uncle go camping in northern Minnesota, where their discovery of an abandoned cabin and a bald eagle leads them into danger, testing Lassie's devotion and Jimmy's faith in God.
Trapped in the back of a truck, Lassie emerges far from home, but with God's help she begins the long journey back, ending up at a circus where Jimmy finally finds her.
Little did Jimmy and Sarah know that spring break in New Mexico would be such an adventure. An encounter with quicksand, a flash flood, getting lost, and scary Indian ruins all lead to a week they will never forget.
