Set in the Ontario cottage country, Porcupine Lake follows two preteens dealing with their volatile desires and the chaotic, messy emotional lives of their parents and older siblings.
Bea is newly arrived from Toronto, and painfully lonely. Her parents are fighting over what to do about the family-owned diner. Kate has lived in the area all her life, along with her absent, constantly hungover mother, her troubled older brother, Romeo, and her angry older sister, a single mom herself. Drawn together by curiosity, desire, and their fascination with and fear of the looming world of adolescence, the pair forge a deep bond — despite objections from those around them about how short-lived their friendship will be.
