The Outer Limits

When Henderson James smuggles to Earth a highly dangerous Megasoid, it escapes, hiding out in a space zoo. Lacking the courage to hunt down the Megasoid, James clones himself and sends his duplicate to do the job. But if the duplicate is not destroyed before James' memories set in, James II will be indistinguishable from James I. Will James' neglected wife, Laura, find renewed love with the less cynical James II? Or will his fear of losing her lead James to summon up the courage to kill?
