A Man from This Star (1958)

Office clerk Eero Koskinen prefers to spend his nights drinking and reminiscing the war with his friends, instead of taking care of his wife and two children. A two-week drinking spree gets him fired, and a new job is not easy to find because of his reputation. He goes to a rehab centre in the countryside for a couple of weeks, but with no permanent result. Meanwhile, his wife has to get a job and is employed by her old sweetheart, now a recently divorced successful businessman.
