Peter is fed up with his father’s unfulfilled promises to visit his friend Zoran, who moved far away with his parents some months ago. He forces his father to sear he will fulfill his promise. Peter immediately tells his friend the good news, and because Zoran doesn’t believe they will really come, Peter swears he will come if he has to do it alone. The next day, Peter’s father postpones the visit once again and rushes to work. But Peter doesn’t want to break his promise and sets off to visit his friend alone. Peter’s younger sister Petra attempts to reveal what is right and what isn’t in the events that follow - and when she finds the solution - it’s a surprise for everyone.
