For Kevin Tippler, drinking has ruined his life. His wife has left him and taken their eight-year-old son with her, but to convince her to come back, he'll not only have to join AA and toss out all his booze, he'll have to survive an apocalyptic virus that turns its victims into raging mutants with a hunger for human cuisine. Worse yet, when his wife and son get infected, all they want to do is kill him. However, there's hope in a serum that could save them, but to get his hands on it, he'll have to stay sober, traverse a devastated cityscape, and battle the hordes that roam the streets...after sunset.
