Sam je oče sedemletne Lucy. Čeprav je duševno zaostal, je njegova nesebična ljubezen do hčerke neomajna. Lucy mu pomeni vse na svetu, zato je čisto obupan, ko mu jo socialna služba odvzame in jo namerava dati v rejniško družino. Sam je odločen, da se bo na sodišču boril zanjo, čeprav je njegov boj na videz obsojen na propad. Njegov primer zastonj prevzame odvetnica Rita Harrison, s katero postaneta nenavadna zaveznika. Skupaj poskušata prepričati pravni sistem, da si Sam zasluži, da hčerko dobi nazaj.
Sam Dawson has the mental capacity of a 7-year-old. He works at a Starbucks and is obsessed with the Beatles. He has a daughter with a homeless woman; she abandons them as soon as they leave the hospital. He names his daughter Lucy Diamond (after the Beatles song), and raises her. But as she reaches age 7 herself, Sam's limitations start to become a problem at school; she's intentionally holding back to avoid looking smarter than him. The authorities take her away, and Sam shames high-priced lawyer Rita Harrison 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.
