The action happens in the 1960s in Moscow. The story unfolds over several
days in the life of a young man by the name of Petya, who has fallen in love
with a mature and experienced girl, who herself cannot not understand her
feelings. A love triangle, pursuits and escapes, drama and funny meetings
are intertwined in this film in a fantastic manner. This all is accompanied
by a partly animated, amusing story about a cosmonaut-dog, made in the
style of Soviet cartoons of the 1960s.
