Floodwaters surround a suburban villa, where Summer has prepared an inflatable boat to escape. Her mother-in-law, brother-in-law, and husband board the boat first, insisting on bringing their expensive pet dog, which takes up her spot.

A helicopter eventually picks her up and takes her away; this disaster has revealed the true nature of everyone involved.
