Martha wakes up one morning and gets ready, listening to music, brushing her teeth and cramming in breakfast like any other day. But this is no ordinary day. When she leaves the house she shares with her mother, she realizes that everyone has disappeared, and she is the last person on Earth.
Martha doesn’t quite know what to do, spending her time wandering and listening to the last message her mother left on their answering machine. But then she finally encounters the one other person left on earth — and discovers they are connected in a way that will alter their existences forever.
