Aris, a race driver, meets a guy who looks incredibly like him. With evident curiosity he tries to find out, from his friend Dimitris, who this identical "stranger" is. He finds out that his name is Kyriakos and that he works in a car-repair shop. Kyriakos too, however, who is involved with Foteini, is informed of Aris' existence and also, from his own father, he finds out that Aris is his twin brother who had been given up for adoption to a well-off gentleman, Kaisaris. The latter, as Ntiana, Aris' friend, finds out, wanted a son to inherit his vast fortune. Ntiana helps Kyriakos become a singer, while at the same time blackmailing Kaisaris. In the end, the two brothers find out everything, and Kaisaris is forced to sabotage Kyriakos' car, so as to put him out of the running in the forthcoming race. At the last minute, however, Aris takes Kyriakos' place. The weak (as usually) heart (of Kaisaris) fails, but Kyriakos manages to save his brother from an undeserved death.
