Robotech
Star Dust
E10 May 5, 1985 TV-PG
The Robotech Masters subject human prisoners to a series of mental probes, to determine the extent of their knowledge of Protoculture. Their concern is twofold: without Protoculture, their civilization will crumble; and eventually their archenemies, the Invid, will sense the presence of Protoculture on Earth... and come looking for it!
