The game is centered on twins Alyson and Tyler who travel to their childhood home in Alaska and must come to terms with events from their childhood, particularly for Tyler as he has
transitioned to male since then. The story involves how their childhood situation influenced Tyler's development and effects on their mother. Dontnod stated that Tyler is the first
transgender playable character from any major studio, and they had worked with
GLAAD to make him an "authentic representation of the trans experience"
