It's A Terrible Life
Dean and Sam are living very normal and separate lives. Dean awakens to find himself in an alternate reality in which he is a Wall Street tycoon who enjoys health drinks and listens to news radio instead of rock stations. He works at a company called Sandover Bridge & Iron Company alongside Sam who is in Tech Support. It seems as if the two do not know each other. Neither has memories of their previous lives.

However, after co-workers start committing suicide at an alarming rate, the two find themselves working side by side to solve the murders.
