Ich war in Honolulu - wetten?

Uwe is a chemistry student and works as an excavator driver on various construction sites at weekends. One weekend, he meets the nursery nurse Gabi. As it turns out later, they owe their encounter to the daughter of the construction site brigadier Trunzer. But it doesn't stop at this one encounter and the resulting flirtation, as the two fall in love within a very short time. On another weekend, Uwe accompanies Gabi to visit her family. When construction site brigadier Trunzer returns from vacation a few days later, he first asks Uwe where he has been during his absence, to which Uwe replies: "I was in Honolulu - bet?".
