The 70th episode of Gene Roddenberry’s science fiction series Star Trek airs on NBC. Frank Gorshin (Batman) guest stars. 
Stardate 5730.2: Two natives of the planet Cheron are brought aboard after one of them helps the Enterprise chase the other down after he had stolen a shuttlecraft from a Federation starbase. Bele and Lokai, however, have a dispute that goes far beyond a simple pursuit of a criminal. Their hatred – and, indeed, the entire shuttlecraft incident – is rooted in a deep racial prejudice which threatens to engulf not only them, but the Enterprise and Kirk’s crew.
