The host has the task of finding video evidence of gay animals. I give the documentary a high rating because the video evidence simply speaks for itself, and is rare enough that it is both shocking and wonderful to see. Maybe this is less important now due to the internet and avenues like Youtube. But we didn't have Youtube back then.
In three longer segments, the host investigates gay swans (finding a three-way relationship with two males and a female), a gay dog murdered in a hate crime (maybe), and plenty of gay sheep, complete with evidence of a physical difference between gay and straight male sheep.
Shorter attention is also given to gay bulls and rams, a group of lesbian seagulls, and various gay primates.
Of particular importance is the absurdly desperate insistence by homophobes that there are no gay animals even when given ample scientific and/or video proof. One person says that the animals must have been trained to be gay. Another says that they are "bad" and therefore we shouldn't look at them.
Last, it's interesting in these times to recall that this video was first aired in the year that the anti-gay Federal Marriage Amendment was first introduced in the US House of Representatives, and the year before (human) gay sex was legalized across the USA, and gay marriage legalized in parts of Canada. It's a reminder of how the world has changed recently.
