Just outside Jullerup Færgeby, three children named Anton, Kaja, and Knud live with their parents in a lighthouse. Every day, the three children row into town to go on treasure hunts with their friends Vera and 44. Among other things, they find a secret cave, which they call "HH." Jullerup Færgeby is also home to old Captain Gus, who follows all the daily events in the town. He watches when the cutter comes home, when the oversized fish export truck drives through town, when the man in the crane is constantly unlucky and shouts "It's stuck", and when Anton repeatedly tears his trousers.

Andrea sings with Ole in the wild sky because she loves to sing. Together, they watch a long list of their many favorite songs, which of course also feature Karla and Kaj. Look forward to revisiting some of Kaj & Andreas' popular and beloved songs. See and hear, among others, Bakke Snagvendt, Kaj & Andreas duet, Kaj's song, Tre små soldater, Prinsessesangen, Prutte-bøvs, Se min kjole, Højt på en gren, Bom tjikke bom, Logre logre, Stærkere end du tror, Andreas sang, Super-Kaj and many more, and you are welcome to sing along.

It's Christmas Eve and everyone is busy preparing for Christmas, but Kaj can only think about the presents he's going to get. Ole and Kaj cut down the Christmas tree in the summer, so of course it has lost all its needles – but it will be fine anyway. They also play hide and seek with the baby Jesus.
