In nature, some bird species will try to get another bird species to raise their young by secretly laying eggs in their nest. This is called brood parasitism. The movie Vivarium takes this concept and applies it to humans. Tom and Emma get trapped in a weird subdivision called Yonder, and are given a baby to raise. It quickly becomes apparent that this baby is not human, and they have to figure out what is going on or risk dying in this place. We look at a lot of strange physics in this movie, as well as Mobius Strips, Changlings, mimicry in nature, and the labyrinth of the Minotaur.
