The FATHER OF FOUR-family is set on a difficult trial when Uncle Anders’ twin brother, Sofus, returns from Australia. The father almost regrets, that he taught his kids to be polite and hospitable, as Uncle Sofus is both mean and grumpy, commands everyone around, and even brings a cow along. The kids quickly grow fond of the cow, but growing fond of Sofus is a bit more difficult. The family – led by Per – must teach the demanding Uncle Sofus how to behave in a real family.
