The brothers Ingemar and Gustav are enemies and have split the business in two. Gustav runs a chainsaw repair shop and Ingemar still runs his motel business and has hired the impossible carpenter Lufsen and Virena. Ingemar has now organized a singles party, but it all seems to be going down the drain as there are only two people registered, mother and son Bengtsson, but are they really mother and son? Is the "hungry pensioner" Hans-Rutger Vällingstråhle really just looking for lunch, or is he also looking for a woman?
