Mason Stark hates his life. A year ago, he lost his wife Kristin to a mugger's bullet and he still blames himself for not doing more to protect her. And today, he was fired from his job. With a gun in his hand and a severance package on his desk, Mason finds himself torn between suicide and psychosis - between killing himself and killing his co-workers. But before he can do either he's pulled into another dimension, into a world where there are hundreds of Mason Starks, each with a different life and a different character. The version of himself that brought Mason here is a powerful, manipulative man - we know him as Stark - who, in this dimension, runs the same company that fired Mason. Stark explains that he built a machine, the Quantum Mirror, to explore all those different versions of himself, only to have his experiment go horribly wrong because he pulled a murderous version of himself, a man we know as Mace, into his reality.

The four people gathered in the top-secret research facility seem at first to have nothing in common: Ford Maddox (Harry Hamlin) is a former spy, Rachel Sanders (Nicole Deboer) is a nurse, Roger Beckersly (Aaron Pearl) is an Army Ranger and Louise McDonnaugh (Bridget O'Sullivan) is a computer programmer. What has brought them together is their telekinetic ability, a talent that Mr. Brown (Robert Guillaume), a CIA project head, hopes to exploit through the use of Teeks, devices that amplify telekinetic power. At first, Brown tries these individual's talents out on simple tasks - moving or crushing a granite block with their minds - but soon his true intentions are revealed. Their first real assignment, says Brown, is to use their powers to kill a Balkan terrorist leader and war criminal. Rachel objects to the assignment on moral grounds, but Brown forces her to take part by threatening to send her brother to jail for life.
