Liebe am Fjord - Der Gesang des Windes.

During Kaare and Hanne Eliassen's 25th anniversary, their teen model son Daniel, who was biting side pains until his exams, collapses and is diagnosed with potentially fatal chronic renal failure. Both parents are ready to donate a kidney for transplantation, but neither matches and Kaare discovers Hanne's 20 years secret: Kaare being presumed near-infertile, she had a 'loveless' but siring affair, which also generated Daniel's brat sister Emma, who encourages Kaare to fall for divorce and disown Hanna. Daniel needing a donor, Hanne desperately searches his biological father, who left town and has a rather common name: Leif Sörensen, only reported found by desperate radio appeal. The meteorologist lives in an island lighthouse, so Kaare, Hanne and Emma, who gets a mutual crush on helpful young fisherman Ronny Stene, sail hurried to the only man who can heal medical urgency, wondering what it will do to relationships, and Daniel finds out to.
