Normally, the Anderssons spend their summer holidays on a camping site. This year, however, Rudolf, the frugal head of the family, is compelled to invite his wife and three children to Greece, because it initially seemed that Rudolf's superior at the tax authority would pay for the expensive trip within the framework of a business trip. But even his spare time Rudolf carries on calculating: While his wife Karin meets an old school friend at the resort, his daughter longs to be at home with her boyfriend, little Håkan keeps causing stirs and the teenage Rune falls deeply in love, Rudolf stubbornly documents the costs for all and everything - after all, “all included” must pay off! The turbulent holiday fun around Rune and his amicable, crazy family provides a sunny cinema delight in which relaxed entertainment is a “family value” of the highest order.
