Los agentes del 5º grupo

Duran and his team of the fifth group are secret agents missioned by Inspector Peña to find and capture a gang of dangerous criminals who are planning a major hit.

El cerco

A group of robbers assault a factory in the port of Barcelona, but, upon being discovered, they are forced to flee hastily, each one his own way. An exhaustive police device is then initiated with the aim of capturing them. But the police persecution to which the members of the gang are subjected incites distrust between them and, one after another, they will fall, until only two remain.
