In collaboration with a Swiss railway worker and a Swiss secret service man, Italian partisans destroyed 64 Tons of explosives in a coup on April 21, 1945 and thus protected the Simplon Tunnel, the connection to Italy, from possible destruction by German army units. In the field of tension between archive material, personal experience and oral tradition, Werner Schweizer conveys a vividly complex picture of this action and its background in an interplay of knotting and unraveling. Some that seem a bit too operetta-like "action" scenes emphasize the quality of documentary sequences even more clearly.
