Two best friends are on a cabin trip to Lake Sunshine. After an unexpected phone call their lives will be changed forever.

Vebjørn (soon to be 30) has never had a girlfriend. He works as a mascot and ski instructor at a skiing resort. One day he crashes into the ski tourist, Polina, ruining her holiday. While he tries to make up for the accident, unexpected chemistry between the two arises. But Vebjørn's anxiety around girls soon catches up with him, as he struggles to get over the idea that no one can like him in a romantic way.

The night is still young as a drunken choir awaits in the hallway. Will Nina let them into her party or not? And is it even a party?
