Daddy's Home One father too many

Becoming a father is not difficult, but being a father is very difficult - Brad (Will Ferrell) would sign this immediately. He tries his best to be a good stepfather for the two children of his new wife Sarah (Linda Cardellini). But the kids don't really like him, and they run him down at every opportunity. Nevertheless, the clumsy radio employee, not exactly the brightest light in the cosmos, doesn't give up. Until a phone call turns his whole world upside down: Dusty (Mark Wahlberg), the children's biological father, announces his visit. Brad's determination not to let himself be displaced by the irresponsible producer is gone when he meets him for the first time: Dusty is a free spirit - super cool, rich and wildly determined to win back his family. A merciless competition for the favour of the children begins. Casual and fickle against daft but eager: Who will win the duel?
