Ten-year-old Laure (Zoé Héran)'s family relocates to a new apartment. With cropped hair and outfits consisting of shorts and T-shirts being the norm for Laure, new neighbour Lisa (Jeanne Disson) assumes Laure is a boy and so Laure takes this opportunity for gender exploration and assumes the name Mikaël. As Mikaël, Laure has a confidence that eludes them as a girl and they are soon adopted and admired by Lisa and the local youngsters.
