Time Blender — Michael Dorn

After cultural anthropologist Tony Millers plane is blown off course, he must land on a strange tropical island. The natives capture Miller and force him to run a deadly gauntlet through the jungle towards a strangely glowing boulder that they worship as a god. With a combination of luck and resourcefulness, Miller is able to quell the natives, and return to his lab at UC Berkeley to examine part of the boulder. But enroute, during a raging electrical storm, the rock is dislodged, crashing to earth... literally ripping Time/Space in the process.
