On a remote Icelandic island, teenagers Birta and Selma rescue pufflings (young puffins) from imminent danger; as pufflings leave their nests for the first time, they often get lost, mistaking the harbor lights for the moon. Over the course of one night, we follow Birta and Selma as they take it upon themselves to counteract humanity’s damaging impact on nature, exchanging nighttime parties for puffin rescues.
