Frihed forpligter.

Danish social democratic propaganda film. During the Occupation, the young freedom fighter Søren had a good working relationship with a comrade in the resistance movement, despite the fact that Søren was a social democrat and his comrade a communist. After the liberation in May 1945, the differences that had been less important during the war begin to stand in Søren's way. Both his friendship with his comrade and his relationship with the wealthy Inger fall apart in the summer of liberation. But through his work in the Social Democratic Party, Søren experiences a renewed enthusiasm and resumes his relationship with Inger. Together, they actively engage in the party's work and both see it as an extension of the struggle for freedom during the occupation. Denmark's entry into NATO is particularly important.
