Tall, dark, androgynously handsome, Pierre wears eyeliner and a black lace g-string, while having sex with both boys and girls. The confusion only goes deeper when the teenager’s single, working-class mom is arrested for having stolen him (and his “sister”) at birth. Thanks to the wonders of DNA, he’s returned to his biological parents: bourgeois, straight-laced and thrilled to have him back—at least until he joins them at a bowling alley in a zebra-print mini dress. The turmoil of adolescence is plumbed with wit and compassion by writer/director Anna Muylaert, whose earlier film, The Second Mother, also dealt with familial loyalty and class tensions. Actress Dani Nefussi gives completely believable knock-out performances in the role of both mothers, and newcomer Naomi Nero makes short shrift of anyone’s expectations as a broodingly intense, potentially volcanic six-footer in stiletto heels.
