September, 1983. Fourteen-year-old Bo, a boat person from Vietnam, lives in a small house in the Junction neighbourhood of Toronto with his mother, Thao, and his four-year-old sister, who was born severely disfigured from the effects of Agent Orange. Named Orange, she is the family secret; Thao keeps her hidden away, and when Bo's not at school or getting into fights on the street, he cares for her. One day a carnival worker and bear trainer, Gerry, sees Bo in a streetfight, and recruits him for the bear wrestling circuit, eventually giving him his own cub to train. This opens up a new world for Bo--but then Gerry's boss, Max, begins pursuing Thao with an eye on Orange for his travelling freak show. When Bo wakes up one night to find the house empty, he knows he and his cub, Bear, are truly alone. Together they set off on an extraordinary journey through the streets of Toronto and High Park. Awake at night, boy and bear form a unique and powerful bond. When Bo emerges from the park to search for his sister, he discovers a new way of seeing Orange, himself and the world around them.
