Casper has left Iben and moved to a hotel. And Mia has finally gotten pregnant. Frank makes decisions that cast doubt on whether he is for women or men, while a bag of pork belly brings him on edge with an accountant, a Muslim and a taxman. And are there explanations that are good enough to defend that Frank is running around in underwear in public places?

Frank and Mia are burning hot at the same cottage as Carøe and Susan, which puts the couple's friendship to the test. Frank and Casper shop erotic toys in Butik Paradis and become involved in a case involving a smurf CD, the police and a driving license in a thin thread. All of this unfortunately happens with Frank's in-laws as witnesses.

Frank and Casper have decided to sponsor the monkey Ditmark in the zoo. Casper pushes for more privileges than sponsors usually have. And one night in the city, it all runs off with them, and they end up in the zoo with two girls. It gives Frank and Casper trouble with a monkey lock, a pair of girl panties and a furious accountant.

Mia has invited Frank on a weekend stay at Skodsborg Hotel. Something gets in the way and to complete the trip, they become "partners in crime". Casper gets lost on Zealand, and Frank has to get him hospitalized again. It seems like things are in order, but a table tennis match, the Kama Sutra and a German gut flush are more than Mia wants to be a part of.

Frank and Mia are looking at houses. The previous owner's wife is dead, but the body has never been found. Frank finds a bone in the garden, and his stubborn eagerness for the bone to be checked leads to shards in the joy of him and Mia. This is how it goes when Niels Hausgaard inaugurates Frank and Casper in the secret behind the "Bispebjerg trick", which is the closest you can get to having sex with someone other than your partner, without being unfaithful.

Casper is still struggling with his bad mood and is unable to work. While Frank impatiently waits for his colleague to come to terms, he wearily joins Mia in the tea shop. To his great delight, he receives an offer from the Angora boys but still refuses when Casper suddenly wakes up and launches plans for them to do the project "Copenhagen Showboat" together. Casper is back in the fight and Frank is happy. Mia does not care, she is more concerned with having a visit from her 12-year-old nephew. Frank thinks there is "something wrong" with the nephew and Mia's dealings with each other, and Frank's attempt to make Mia understand it sends him straight back into the trade.
