2011 French film directed by Céline Sciamma (who previously directed ''Water Lilies'').

Ten year old Laure is used to moving around. She's moving once again, but this time her parents plan on staying in a suburb for a while.

She meets Lisa, a girl her age, who mistakes her for a boy. Laure introduces herself to Lisa and the local children as "Mickaël". She keeps this secret from her parents, and it is summer so she hasn't ran into any problems with school yet. She also develops a mutual crush on Lisa.

Not to be confused with ''Film/TommyBoy''.
