Mary and Gary wonder if they can ever be “normal parents” when they need to werewolf-proof their basement. On top of their existing parenthood worries, they’re concerned about the species of their future baby.

Things could get hairy as a full moon approaches. Mary must transform while heavily pregnant, testing the limits of the new basement door. As a precaution, Emma spends the night at her aunt’s house.

The wolf didn’t attack Emma and Gary while they were in the car in the outback and doesn’t recognize them during a rampage through the house. When Gary meets a normal woman, the mother of Emma’s new best friend, Mary gives him an easy out.

Mary’s former professor Anton shows up, threatening the precarious balance and revealing something that complicates things even further. As a second full moon rises, Mary contemplates letting her wolf run free while stuck in the basement with Anton.

In the aftermath of Mary and Anton’s brief but significant encounter as wolves, Gary confronts his rival. Gary thinks it’s a sign from the universe when he crashes into who he thinks is the same person who fatefully brought him and Mary together.

At the eight-month mark, Gary has the birth plan mapped out and all the couple needs is zero stress until after the full moon. When the cops call asking questions about a double homicide, Mary’s water breaks.

A maternity ward is the worst possible place for Mary to be on a full moon. When an emergency C-section is ordered and the cops show up, there’s no other option for Mary, Gary and their imminent baby or wolf but to run.
