The film combines old newsreels, nature footage featuring cane toads in action, re-enactments of toad-related events, and the first-hand accounts of people's interactions with the toads. The story begins with the toads in full form 15 million years ago, and fast-forwards to the 1935 introduction of 102 cane toads to Australia in an ill-conceived attempt to take on the cane beetle devastating sugarcane crops. The toads' proliferation got out of hand, and they became a seriously invasive species, marching across Australia, capturing huge swathes of territory over the decades. Various characters, including scientists, farmers, and everyday people, provide testimony about the creatures.

Ice People brings Anne Aghion and her crew to Antarctica where they spent four months following the lives of North Dakota State University geologist professors Allan Ashworth and Adam Lewis, as well as the McMurdo Station staff over four months.

The film shows the scientific team scouring ancient emptied lakebeds in the hope of finding evidence of plants and insects that would prove that the world's coldest continent was once warm and verdant roughly 14 to 20 million years ago.
