Alex and Anna have craftsmen at home and are forced to live with Alex's mother Margareta over the weekend. Margareta reveals that she met a new man, Tord Malmberg, the disgusting neighbor from childhood. Alex now has to deal with the mother's new love with everything it means.

Alex accidentally touches his female patient in the dentist's chair. The rumor spreads and a feather soon becomes a hen. Rumor does not get better because Anna, during a girl's dinner, finds traces of a very hesitant internet use in Alex's computer.

Fredde and Mickan decide to go on a romantic castle weekend with the hope of strengthening their relationship and arguing less. Anna doesn't really fit into Saltsjöbaden's mother group and the thing doesn't get any better when she and Alex leave for a child-free weekend.
