Samo, Sandi, and Krištof are preparing for their final exams. They come up with a plan to get hold of the math exam questions with the help of the professor's daughter, nicknamed Hyperbola. Since they don't know her real name, they call her Vesna (Spring). Unexpectedly, the professor's real daughter, the attractive Janja, shows up on a date. Samo and Vesna fall in love and the story begins to unfold rapidly. Samo invites Vesna (Janja) for a ride in a glider. They have to make an emergency landing. Sandi, happy that they finally got their assignments, fights with Samo over them. Samo gets injured and can't go on a date with Vesna. Sandi goes on the date instead, trying to win Vesna over. She scolds him and he reveals the truth that they drew lots for Vesna. Because of this, Vesna wants to kill herself. She jumps with a parachute, hoping it won't open. Everything turns out fine, and the parachute opens.
