After yet another friend makes a surprise pregnancy announcement, a dejected Natasha heads to a remote cabin to get her head straight – only to be confronted by exactly what she sought to get away from: a baby.

Inexplicably reunited with the baby, Natasha scrambles to locate his mother and uncovers an alarming pattern of events on a thumb drive. Later, after her friends confuse the situation further, Natasha reaches out to her estranged sister Bobbi.

Despite Mrs. Eaves’ shocking solution to her baby problem, Natasha finds herself willing to do anything in exchange for her help – even if it’s the herculean task of nap time. Meanwhile, Bobbi and her partner Sam prepare for an important meeting with their adoption social worker.

With the baby now in Bobbi’s hands, Natasha must reunite with her mother Barbara, whom she hasn’t seen in fifteen years. While Bobbi discovers an unmatched ability to put the child to sleep, Natasha confronts her family’s fractured history, and Barbara celebrates having children and grandchildren under the same roof.

As Natasha and Mrs. Eaves remain trapped in Barbara’s summer solstice ritual, the baby’s complicated origin, connection to Mrs. Eaves, and trauma-filled path to Natasha are revealed.

Desperate to leave the Jupiter House, Natasha, Bobbi, and Mrs. Eaves find their plans thwarted by the chaos and destruction of the other suddenly-possessed children. Later, Bobbi receives the social worker’s long-awaited call.

Natasha decides to give the baby exactly what he's after amid growing concerns from her father Lyle, Bobbi, and Mrs. Eaves, who each go to great lengths to ensure her survival.
