Sean Penn stars in this drama as Sam Dawson, a developmentally disabled adult who has been working at a coffee shop and raising his daughter Lucy (Dakota Fanning) for seven years. Sam receives help in his parenting duties from a circle of trusted confidantes, including his ADD-afflicted best friend Ifty (Doug Hutchison), the paranoid Robert (Stanley DeSantis), an agoraphobic neighbor (Dianne Wiest), and his other disabled pals, Brad and Joe (played by real-life developmentally challenged actors Brad Silverman and Joseph Rosenberg). Although he provides a structured and loving environment for Lucy that includes regular visits to IHOP, video nights, and karaoke, Sam's daughter is beginning to surpass him in mental acuity. When Lucy begins intentionally stunting her own growth so as not to hurt her beloved father, social worker Margaret (Loretta Devine) takes action, removing the girl from her home and placing her in the temporary care of a foster mother, Randy (Laura Dern). As the day of his hearing looms, Sam seeks out the aid of driven, obsessive lawyer Rita Harrison (Michelle Pfeiffer), who takes the case only to prove to her colleagues that she is willing to accept pro bono work. Opposed by county lawyer Turner (Richard Schiff) in court, Rita gradually comes to care for her client and his daughter, even as they force her to consider the limitations of her own abilities as a parent. The soundtrack for I Am Sam (2001) gained considerable critical attention, consisting entirely of Beatles cover songs by such contemporary artists as The Black Crowes, Eddie Vedder, the Wallflowers, and Aimee Mann, among others.
