Sam Dawson has the mental capacity of a 7-year-old. He works at a Starbucks, is obsessed with the Beatles and has a daughter with a homeless woman who abandons them. As the daughter reaches age 7, Sam's limitations start to become a problem. When the authorities take his daughter away, Sam shames a high-priced lawyer into taking his case pro bono. In the process, he teaches her a great deal about love, and whether it's really all you need.
