Robert Culp appeared in 3 Outer Limits shows, and all are high quality. In this one he is a volunteer to undergo a complete modification of his body to frighten the world uniting in an effort to repulse a supposed invasion from another planet. His new body is modeled on something in a box which we never see, and which apparently came from another world without much explanation. It's Culp's usual underplayed hero that keeps the episode focused.
