Having suffered a tragedy, Ben becomes a caregiver to earn money. His first client, Trevor, is a hilarious 18-year-old with muscular dystrophy. One paralyzed emotionally, one paralyzed physically, Ben and Trevor hit the road on a trip into the western states. The folks they collect along the way will help them test their skills for surviving outside their calculated existence. Together, they come to understand the importance of hope and the necessity of true friendship.

The Fundamentals of Caring gets maximum mileage out of the chemistry between its well-matched leads as it follows a fairly well-worn coming-of-age road trip route.
