The Buried Life

The series focuses on 4 friends (Duncan, Ben, Dave, and Jonnie) as they travel across North America in a purple transit bus to complete a list of "100 things to do before you die." For every item they complete on their list, they help a stranger achieve one of their dreams and encourage others to go after their own lists. Everywhere they go they ask the question: What do you want to do before you die?
