Lieutenant Berti, who is supposed to carry out the action with him, is slightly injured after a climbing accident and is therefore not fully operational.

Berti pretends to have dragged himself injured to the mountain hut and is taken to his house by Stefan, where his niece Sandra is caring for him.

Stefan, who used to be an active smuggler, actually wanted to retire from the business, but his former boss forces him to join a big smuggling spree.

Because of his injuries, Berti cannot take part in the rise and arrest of the gang and coordinates the attack on the smugglers over the radio.

As a result, Berti is shot; Mauri ends up shooting Stefan; the surviving smugglers are arrested.
