After an injury leaves him with a cybernetic leg and no job, Dr. James Watts finds himself becoming roommates with a private detective named Sherlock, who is trying to emulate his literary namesake, to a disturbing degree. Watts is soon whisked along on Sherlock's cases, from solving murders to exposing immoral Corporations. He may or may not be crazy, but one thing is certain; life with Sherlock will never be boring.
