Stockholm silver spoon boy Markus Boyson takes his fiancée Katerina to hotel chain owner Frederik Hamsun's own favorite, in the Swedish countryside, but she refuses to follow him on a summer trip around half the world at his dad's expense. She rather accepts Frederik's mysteriously unprecedented job offer as staff apprentice. It turns out Frederik's summer job driver, architecture student Lasse Lundin, is the hunk she bumped into during water sports, and a tempting alternative. Frederik's generosity ties in with the secret of grandma Nele Lindberg, who raised Katerina.
