S4, E18: 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 a junky and small-time crook to jail for life. With Rachel on board the assassination is a success as is the elimination of a pesky African revolutionary leader. But the telekinetic powers produce unexpected side-effects and soon the killers find that they have become the prey.
