The Other Side (2020)

Aubrey, a spunky, adventure-loving teenage roleplayer, sets out on her first live-action roleplay trip (LARP) with her best friend James, following a map that leads to another roleplaying book. Her annoying little brother Brendan tags along, but she evades him by sending the boy off alone on a separate journey. However, once Aubrey and James get deeper into the woods, they discover that the map has led them through a portal to a fantasy world. Aubrey is fascinated by the reality of the new wonders around her, but stops short when she finds that desperate Vikings have kidnapped her brother to appease a dragon that terrorizes their village. Determined to save him, she goes to battle with Lord Berinon, the town leader, in an effort to save her brother from a fiery death before it's too late.
