Panos and Archimidis are colleagues and co-tenants. Panos is a modern young man, whereas Archimidis is more conservative. Panos tries to make Archimidis live his life more passionately. Archimidis then develops a dual personality. In the morning, he is a restrained teacher, and at night he is a reveller and a skirt-chaser. When his sister is kidnapped, Archimidis enters a hospital to overcome his problem.
