Oh, Charles!

Karol (Jan Piechociński), a young architect, leads a successful professional and social life. Happily married to Maria (Danuta Kowalska), he simultaneously attracts several attractive women: Wanda, Paulina, Irena, and Basia. He does not refuse their company but begins to worry about how to manage his "erotic friendships." He is popular with women and wins an architectural competition, but one day, upon returning home, he finds his wife and three mistresses trying to run the household together and share care for him. The fantasy of polyamory turns into a nightmare—Karol seeks escape with friends, in alcohol, and meets even more women on the construction site. On top of that, another possibility arises—a wife and four lovers under one roof, intensifying the chaos and confusion in his life.
