June and Moira undertake a perilous undercover mission that tests their courage and resourcefulness. At the same time, both Serena and Nick face critical crossroads, making decisions that could have lasting consequences for everyone involved.

The family is reimagined as animals in a nature mockumentary. Narrated in the style of National Geographic, the episode follows Homer and Marge as whales from different species drawn together by instinct, Bart as a newly hatched iguana fighting to survive against relentless predators, and Lisa as a finch leading her flock toward innovation. As each character faces the challenges of the natural world, familiar faces from Springfield appear in unexpected ways, bringing a fresh perspective to the struggle for survival in the wild.
