The story of Greek patriots' struggle against the Nazi invaders in May 1941, when German troops landed on the island of Crete. Fleeing the Germans, seven people, completely different in their views and personalities, come together: communist Memos, who has escaped from prison; military doctor Kimon, fleeing from the hospital; nurse Alika and nurse Krinjo, a gendarme; and two soldiers—a Greek and a New Zealander who has fallen behind.

A crime has been committed. Thanks to the determination and perseverance of a young police criminal investigation officer, it is possible to get on the trail of a seasoned repeat offender and solve a long-standing crime related to the disappearance of diamonds of the famous Siberian merchant Kukhterin in February 1917.
