During German invasion three French soldiers are cut off from their unit and now have to find a way to cross enemy lines without being detected. With a bit of cleverness and huge shear of luck they are on the way for adventure of their lives.
Chaudard, Pitivier and Tassin are again cut off from their unit, but this time by mistake they end up in castle used by Germans to keep high rank officers and they try to find a way to escape.
Two years after their heroic acts Chaudard, Pitivier and Tassin again get involved in adventure, but this time without uniforms - while Resistance tries to smuggle British pilots those three are just in a wrong place in wrong time.
