The Schroeders travel to Thailand for a last family holiday before the kids leave home. In Phuket’s stronghold of mass tourism, Patong, 18-year old Felix falls hopelessly in love with the beautiful Thai girl, Fai. Fai’s parents have sent her to Phuket from their home in northern Thailand in the hopes that she will get over a lost love. Meanwhile, Felix’s older brother, Tommy, is convinced that Fai is a prostitute. Felix is fed up with his brother and with his parents, Annegret and Ullrich. He is head over heels in love with Fai and she returns his feelings. As the vacation draws to an end, Felix and Fai say a tearful farewell to each other. Then, on the way to the airport, the young man makes a snap decision to remain in Thailand. His parents are horrified. That was not quite what they meant when they exhorted him to “follow his heart”. Annegret is incensed. She skips the flight and goes after her youngest son.
