The civil defense warden caught Verne Brown and Marty McFly, on September 27, 1944, trying to break into Emmett Brown's apartment. Shortly afterward, he discovered and impounded the DeLorean time machine.
Without a way home, Verne and Marty spent the night at a victory garden in Courthouse Square. Marty was attracted to Rosie, earning him the ire of Sergeant Frank Tannen. While running away from, Tannen, Marty accidentally enlisted in the United States Army. Meanwhile, Verne befriended Rosie's sister, Dorothy, and soon discovered that when she gets older, she will become his dancing instructor in 1992.
Eventually, Marty managed to escape Frank Tannen and the civil defense warden when Verne and Dorothy entered and won a dancing competition at a USO show. Marty and Verne were able to return home to 1991, and Verne resumed dancing lessons with Dorothy, although he is now enthusiastic about dancing.
