These two young sisters - Clara and Sarah Gagnon - have always lived in the countryside with their parents, in a Christian community cut off from the world. The day Sarah suddenly disappears, Clara falls apart. Convinced that she knows where her sister is hiding, Clara runs away too, in the hope of bringing her back to "the straight and narrow". Clara arrives in Montreal at the home of her unknown Aunt Louise, only to discover to her horror that her sister is not there. When her aunt tells her that she's about to leave on vacation, Clara realizes that she only has ten days to find her sister. As she searches the city, Clara discovers the world, doubt and the price of freedom.
