This film focuses on three men: Horst Knüpfer (Horst Drinda), Jürgen Matthes (Peter Reusse), Peter Vorberger (Jaecki Schwarz) and their relationships with their women. Peter is 30 years old and has - again !! - found the woman for life: Ina Wendler (Ingeborg Westphal). This concerns him so much that his professional interests take a back seat and the disputes between Knüpfer and Matthes have little effect.
