Leif (Peter Fridh) is being blamed by SVT and the newspapers of Sweden for causing a satellite to come out of its regular orbit causing a complete blackout of Sweden's public service channels much to the annoyance of his dentist wife Astrid (Anna-Lena Bergelin).

Meanwhile, a disgruntled man (Carl-Åke Eriksson) is renting out his house due to being fed up by the hauntings in the neighbouring castle.

It becomes apparent that two ghosts, Jean and Staffan, inhabit the castle and are desperate to keep living people away.

They try to frighten the family away, but Astrid, Leif and Melitta ignore them, and Ivar and Lillan become fascinated and try to find proof of their existence.

A friend of Lillan hands over a device that calculates electronic activity and tells her that he has read that ghosts generate electric fields.
