Encho Sokerov, who once owned the largest bookshop in Sofia, is unable to change his views after the establishment of the socialist rule. Left alone with his three children, he wants to give them the best of everything, as he understands it. His oldest son Vesselin has been allocated to the physician's job in a rural area, but stays on in the capital city thanks to a well-known professor who pulls strings. Vesselin's childless wife Nellie insists on their adopting a child. Sokerov's other son, Mircho, is married to a rich woman, Zora. The father has already found a good match for his youngest, the school-leaver Lada, but she falls in love with the telephone technician Boris and wants to tie the knot with him. One evening the two come across a founding. They call her the Tiny Tot and Lada takes her to Nellie. Sokerov does not want other people's children in his home. The baby is taken to the orphanage but Lada and Boris keep taking care of her.
