Stargate: Christmas is approaching, and when their father loses his job as a Christmas tree seller, Ronja and Melissa take over the responsibility. While their father drowns his sorrows in the Stargate pub, the two girls are forced to fend for themselves and dream of a different reality. It is a film about a father who does his best, but is not enough; about an older sister who has far too big shoes to fill; and about a little sister who never stops hoping.
