Tony wants to carry out a perfect robbery and get a lot of money during the celebration of the 24 Hours of Montjuic, a motorcycle race. To accomplish this, he counts with the complicity of Peter, a runner who wants to switch to professional level. Everything is carefully planned, but at the last moment a crime is committed and Peter is trapped in the house of the victim unable to get out as the gate has been locked. The only way to help Peter is that Tony gets a copy of the key that Carmen has, the girl who took care of the victim, before she returns home.
