Stella (Olympia Dukakis) and Dot (Brenda Fricker) have been together for 31 years, faithfully accompanying one another through life's ups and downs. Now in their seventies and with Dot legally blind, they make a bold decision when Dot's granddaughter Molly (Kristin Booth) decides the "best" place for Dot is a nursing home. Forced to become outlaws, Stella and Dot hit the road to Nova Scotia, Canada to get legally married. En route they collect young hitchhiker Prentice (Ryan Doucette), a small-town boy turned "Interpretive dancer" on a journey to reconnect with his distant mother. Despite his bravado, Prentice is a confused and wounded soul who has much to learn from Stella and Dot as they wage their unexpected battle to be legally wed. Equal parts humour and grace, Cloudburst explores life, death and love through the eyes of this unusual trio.
