Ryan Wilson is the last person in the city of Seattle. His family disappears without a trace, and now the only one by his side is his German Shepherd. Ryan enjoys his time alone- frequently exploring the city, shooting rifles, learning how to climb tall buildings, and raiding expensive hotels. But soon, his alone time is interrupted when he is caught by a trap when exploring the outskirts of Seattle, and is taken in by a group of humans he knows nothing about. Soon, Ryan discovers that in this world he is no longer by himself- and that he just may have to sacrifice his life to uncover Seattle's darkest secrets.
