Five friends who have known each other since childhood and always stuck together through thick and thin encounter an evil greater than any of them could every have imagined in this frightening study of the darkness within. When we first meet Max, Jimmy, Norm, Nick, and Jason, they are eighteen year olds who already share a bond closer than that of most biological brothers. They all have high hopes for the future, and aren't afraid to share their dreams and frustrations with one another. Flash forward a little over two decades later, and the five friends are still as close as ever. They've experienced marriage, endured life's frustrations, yet through it all they have always remained open and honest. Every year the group sets out on their annual football outing, and this year the destination is Philadelphia. But tonight, the group will be separated while enjoying the city's bustling nightlife, and the stage will be set for an unspeakable horror. As the ultimate struggle of life or death unfolds in a horrifically painful fashion, friendships will be put to the ultimate test and the true personalities of all involved with shine through a suffocating darkness with the power to consume all five in the course of just one night.
