What Makes Us Boys is a poetic documentary film about two young brothers who grow up in a Dutch suburb. Despite the fights they have sometimes, they know they can't live without each other. Daan is Sam's big brother, someone he looks up to. Sam is Daan's little brother, with whom he shares everything. They are both dealing with things kids their age aren't supposed to worry about. Daan has a rare illness which prevents him doing things other kids can do, while Sam is struggling with his identity as he used to be a girl named Mara.
