Girl Flu.

Bird, 12, has to become a woman whether she wants to or not when - in the worst week of her life - she gets her first period, is ditched by her impulsive, free spirited mom, and learns that you can never really go back to The Valley.
Bird, a smart level-headed tween, and her immature stoner mom gracelessly navigate the arrival of Bird's first period, which she gets on the last day of school… in front of the entire class.
