In March 1983, in Los Alamos, New Mexico, a disfigured man is taken to the hospital. An unnamed police detective tries to question him about a recent murder. While the detective answers a call outside the room, the disfigured man jumps out of the window, leaving behind a note that reads: “I’M SORY ABBY”.
Two weeks earlier, Owen, an unhappy and lonely 12-year-old boy who is neglected by his divorcing parents, sees a barefoot little girl named Abby and an older man moving in next door. At school, a teenage bully named Kenny and two of his friends constantly terrorize Owen, who lies to his mother about it but tells Abby the truth. Abby encourages him to retaliate, and pledges to protect him. Owen and Abby become close friends and start communicating by Morse code through the walls of their apartments.
