The motion picture premiered in Copenhagen and Aarhus cinemas on 12 February 1962 and became a critical and major commercial success.

After working in Greenland for almost nine years, Martin (Poul Reichhardt) returns in 1920 to his childhood home, hoping to benefit from the short-lived economic boom following the First World War.

[3] He takes a quick tour of the now-industrialized city and greets his old friends at the inn, and then visits his puppy love Martha (Astrid Villaume).

He learns that Just is in conflict with his uncle Bent (Jørn Jeppesen), co-owner of the farm, who wants to sell the property before their money situation worsens.

[3] Meanwhile, young farmworkers Henrik (Ib Mossin) and Jesper (Bertel Lauring) share a romantic interest in Just and Martha's daughter Inge (Puk Schaufuss).

As the drunken Jesper makes his way back to Inge, he is pulled aside by Erna (Birthe Lundsgaard), who informs him that she is pregnant with his child.

[3] Back at the farm, Just and his wife meet with their attorney H. C. Holm (Knud Hallest), who tells them the bank will never lend them money as long as they have unpaid loans.

Martha decides to set parts of the farm on fire, hoping to collect the insurance money.

[7] Journalist Svend Kragh-Jacobsen of Berlingske wrote a favorable review of the film on its release date.
