Here, a Sandman (Nicholas Hammond) is given plastic surgery -- courtesy of the New You Laser drill prop featured in the Logan's Run feature film -- to resemble a Runner, Hal 14 that Jessica (Heather Menzies) once befriended.
Logan and Jessica find the idea of revolutionizing their corrupt civilization a tantalizing one, and after encountering the Sandman/runner begin to contemplate the idea of a return to the Domed City. But then, they run into a primitive society run by an all-powerful "Provider." This provider sends out patrols, led by Garth (Spencer Milligan), to protect him from Sandmen.
Another fine element of this episode involves my favorite character: Donald Moffat's android, REM. In this episode, REM must make a choice between saving his friends and committing murder...an act which runs counter to his very programming. Here, he kills Matthew 12, rather than seeing Logan die. He admits to feeling "disturbed" by his action, and this is an intriguing development for the character. In many ways REM is inspiration or the forerunner of Brent Spiner's Lt. Data on Star Trek: The Next Generation. He's learning more about humanity and what it means to "be human" all the time. This week, that learning involves a dark lesson. And he looks absolutely bereft after breaking his “First Law.”
