Robert Gordon is about a totally wacko private zoo keeper, Michael Conrad (Michael Gough) whose literal worship of the animals he tends -- especially the cat species -- starkly contrasts with his cold-blooded disregard for human life. Conrad has a mute son Carl (Rod Lauren) with a simmering Oedipal hatred, and a wife who should have left him eons ago. Whenever Conrad gets miffed with anyone coming a little too close to his private affairs he simply feeds the hapless victim to the animals.
