In this short novella two young people - a soldier and a high-school girl - have to guard their comrades while they carry out an important action - smuggle weapons from a barracks to the anti-fascist fighters. The two have never met before and they have to make up a story of how they met so as to serve them as an alibi in case of failure. Against the background of the imaginary and real the filmmakers reveal the time, the character and the ideals of the young generation in the anti-fascist struggle. In the world of dreams the two young people share different thoughts, have discussions, imagine their future and begin to fall in love with each other. In the world of reality, however, they face risks and deadly dangers.
