A necrophilic street sweeper who cleans up after grisly accidents brings home a corpse for him and his girlfriend to enjoy sexually, but is dismayed to see that she prefers the corpse over him.

Gottfried and Sophie Kummer live freely and independently with their six boys in a modest cottage in the countryside. Although the cottage has neither electricity nor running water and must be heated with wood, the small wages of a construction worker are not enough to meet all their obligations. Especially since the former owner, Mayor Lüthi, still has a mortgage on the cottage, on which the Kummer family must pay interest. And this interest makes life difficult for the Kummer family. Then a stranger appears who would like to buy the cottage as a vacation home. But for the Kummers, it is their home! Mayor Lüthi, however, senses a big deal, promises the stranger the house, and at the same time gives the Kummer family a final payment deadline for the interest until the end of the month. So it is the six Kummer boys who take up the fight to save their cottage.
