René and the Café staff prepare to welcome the invading British troops, and soon find that the invasion party includes a couple of old friends. Lieutenant Gruber and the Colonel are ordered by the General to stay and fight the invaders, rather than surrender. However, seeing as their defeat is almost certain, the two German officers decide to go AWOL, disguised in stolen British uniforms. The second half of the episode is set many years after the war ends. Gruber, the Colonel and Helga, now private German citizens, return to their old French garrison in search of the old friends they made there.
