Each teenager chooses his own way to rebel, but the young protagonist of Andrew Kotting's bizarre comedy/drama finds a unique way of challenging his folks. Ivul (Jean-Luc Bideau) is a strong-willed Russian expatriate living in France with his forbearing wife (Aurelia Petit) and their four children. Teenaged Alex (Jacob Auzanneau) is Ivul's only son, and he's become especially close to his big sister Freya (Adelaide Leroux). Freya is extremely fond of Alex, and shortly before she's to leave for a long trip to Russia, she asks him to touch her in a provocative manner, and he happily agrees. However, Ivul walks in on Alex and Freya, and angrily accuses Alex of taking advantage of his sister. When Alex can't convince his dad that this isn't the case, he angrily climbs up to the roof of the house, hops into one of the many trees that surrounds their home, and stays there. For the next several months, Alex lives in the trees despite repeated requests to come back to solid ground, and the youngster's absence takes a surprising toll on the family. Ivul was the first French-language film from British director Kotting.
