The cinema war-action movie takes place partly during WWII and partly in 1975 in Spain. The main characters: agent Capt. Hans Kloss and Herman Bruner, want to find the stolen treasure, putting their lives at stake.

The film presents the last days of Gen. Sikorski, right before the Gibraltar catastrophe. The commander is accompanied by his daughter Zofia and a group of closest collaborators. They are all guests in the palace of the Governor of Gibraltar, Mason Macfarlane, who is supposed to persuade Sikorski to give back documents on the murder of Polish officers in Katyn. When Sikorski refuses, a plan of attempt on his life comes into action. Who stood behind it? Who executed it and how? Was Zofia on board of Liberator too?

A slightly sinister but charming young man falls in with a young mother and daughter and her boyfriend on a camping holiday and leads them astray.
