The world Cal and Frida have always known is gone, and they've left the crumbling city of Los Angeles far behind them. They now live in a shack in the wilderness, working side-by-side to make their days tolerable despite the isolation and hardships they face. Consumed by fear of the future and mourning for a past they can't reclaim, they seek comfort and solace in one other. But the tentative existence they've built for themselves is thrown into doubt when Frida finds out she's pregnant.
