The Orange Watering Truck (1973)

A new glamour girl, Král Bori, comes to the 6/B class, clever and impertinently charming. Oma, the gang-leader, likes the girl very much. He lives under dreary circumstances, but dreams of becoming a conductor or making a circus carrier. He definitely wants to attract attention. Bori, however, ignores him, but is very nice to his best friend, Totyi.
