Yesterday takes you through a dark underworld where the homeless have started disappearing, and when they are found, they appear to have been burned alive. In a seemingly unrelated event, but just as strange, Y-shaped marks are appearing on the hands of other people. No one really sees a connection between these events, and to make matters worse, the media seems to be playing down both circumstances as well. After all, it's just a strange mark, and who really cares about some dead homeless people.
Enter Henry White. He is a rich and powerful man that puts in a lot of time to help the beggars of the world. Henry sees the deaths that happen in the alleyways and realizes that no one is really looking for the killer. Henry joins forces with his long-time friend, Cooper, to find out just what is going on in New York City.
Meanwhile, another character, John Yesterday, wakes up to find he doesn't remember anything about his life. What he knows is little, only he is a leading expert in Satanism and Henry has hired him to investigate not only the death of the beggars, but also a religious sect that Henry believes is connected to the killings.
As you play Yesterday, you will be able to switch between these three characters and learn more about them as you hunt down what is causing the little-acknowledged deaths. Each character's story unfolds in front of you as various events will cause them to have flashbacks and reveal to you just what kind of person you are playing as.
If there is one thing I can say about Yesterday, it's that it is filled with tons of twists and turns that will leave you seriously questioning the characters you are playing. Yesterday simply provides a wild ride with revelations that would rival the TV series Lost... even if some of them are rather far-fetched and out of left field.
