Factory worker Otto Nielsen and his wife Helga live in a 2-room apartment in a sad Copenhagen suburbs district, where the S-trains still bumble by, but of course, such things can be used to. They have five children and it is often difficult to meet daily expenses. Nielsen has bought a building site outside the city, it is his dream to once again be able to exchange the narrow apartment with his own house.

It all happens over two days and—naturally—and in particular—two nights.
