Leo, a stout, calm, actually boring, but nice fellow ist persuaded by a frivolous friend (who has a wife) to marry his Thai girlfriend in pretence, so that she with a Swiss husband is allowed to stay in Switzerland. Quite funny, how shy both behave, when she reluctantly comes to Leo's flat. But after some time - you may have guessed - the unplanned happens: she begins to like and even love Leo, and turns away from her airy boyfriend. Leo in return also falls in love with her and has a hard time to explain to his mother, that he secretly has married only to do his friend a favour. Things get complicated, as Apia (so the name of the Asian girl) works in a brothel and Leo has to buy out the pimp to free Apia from this milieu. He even fight the Swiss bureaucracy, which got wind of the false marriage without knowing, it has become real love. Leo literally saves Apia in the last minute at the airport when she forcibly is to be repatriated. This eventually convinces the state clerk. The film ends with a surprise for Leo when Apia's whole family arrive at the airport, because all family members should come together, when a baby is due.
