The black-and-white sequences begin with Leonard Shelby (Guy Pearce) in a motel room speaking to an unnamed telephone caller. Leonard has anterograde amnesia and is unable to store recent memories, the result of an attack by two men. Leonard killed the attacker who raped and strangled his wife (Jorja Fox), but a second clubbed him and escaped. The police did not accept there was a second attacker, but Leonard believes he is called John with a last name starting with G. Leonard conducts his own investigation using a system of notes, Polaroid photos, and tattoos. As an insurance investigator, Leonard recalls one Sammy Jankis, also diagnosed with the same condition.

Finding a note in his clothes, he meets Natalie (Carrie-Anne Moss), a bartender who resents Leonard as he wears the clothes and drives the car of her boyfriend, Jimmy
