Lucky Cucumber is a local "celebrity" who is known for many things, such as being "a man who would set another man on fire for a pizza," having had over 100 jobs and living in a cave. A couple of local filmmakers decide to take a government grant they were given and make a film about Lucky and his life. What ensues leads you deep into the world of a bizarre, dimwitted guy who lives with his cranky grandpa and awkwardly goes through life one weird day at a time.
