Sergeant George Merkos is so absorbed in his duties that he never finds the time to meet the relatives of Anna, the girl he loves. Instead of going to her house, he chose to arrest a criminal and then go to the villa of Julia, a middle-aged woman who was found dead. The sergeant's suspicions turn to the murdered woman's young husband, Alekos Petratos, but he has a solid alibi. The meticulous Merkos finally refutes Petratos' alibi, but shows excessive zeal in arresting Dimitris Naskos, whom he mistakenly believes to be the rapist of a young woman. Dimitris, who is Anna's half-brother, is killed while trying to escape, and Merkos is forced to resign, losing Anna forever.
