The year is 2045, global warming escalates, and wildfires are rampant. Vancouver has been devastated by an earthquake and tsunami. Those who have survived have moved north or taken up residence at Little Mountain, the highest point in the city. Food and water are scarce, there are more violent storms and rising temperatures. The ashfall from the volcanoes increases daily, making it difficult to breathe. Four young adults, Taylor West, Carlie Fleming, Mai-Li Wong, and Willie Arbuckle, and three children, twin brothers Rusty and Eddie Coleman, and Debbie, who has Downs Syndrome, have gravitated together, forming a motley crew of survivors, living in constant fear of the violent gangs.

Making a life-saving decision, they decide to walk to the Interior, hoping to find a better life. Inexperienced, they face unknown obstacles, daily hardships, and hunger. Traveling across the devastated Wastelands is fraught with danger with unexpected complications making the journey more treacherous than they ever imagined. Reaching a sanctuary and indeed their very survival hangs in the balance. Relationships are tested time and again. What will remain strong and what will shatter?
