The film follows the story of Ben, a retired writer who becomes a caregiver after suffering a personal tragedy. After 6 weeks of training, Ben meets his first client, Trevor, a foul-mouthed 18-year-old with muscular dystrophy.

One paralyzed emotionally, one paralyzed physically, Ben and Trevor take an impromptu road trip to all the places Trevor has become obsessed with while watching the local news, including their holy grail: the World's Deepest Pit.

Along the way, they pick up a sassy runaway and a mother-to-be who help test the pair's survival skills outside of their calculated existence as they come to understand the importance of hope and true friendship.
