The Red Train(1982)

Captain Angelos and the soldier Memos participate in a group of experienced ELAS's guerrillas. The team assumes the dangerous mission to reach the center of Athens, under the control of the English and the Greek regular army, and blow up the headquarters of the British headquarters located in the hotel of "Great Britain". When after a fight they manage to reach and place the explosives, the order is revoked. Their headquarters were afraid of the consequences of the possible death of British Prime Minister Wilson Churchill, who suddenly arrived in Athens and so the whole business was canceled.
