A young mother (Elisa Moolecherry) clutches her baby tightly while being chased up a dark stairway of an office building by a ravenous Atavus (Brian Jagersky). She bursts through the door of an office with the Atavus following closely behind. Just as he wrestles the baby from her grip, Renee Palmer (Jayne Heitmeyer) appears in the doorway waving a gun. Renee opens fire and is able to rescue the baby, but the Atavus turns on the mother and forces her toward the office window. Renee shoots the Atavus as he pulls the mother through the window. He falls to his death while she clings to the window ledge by her fingertips. Renee tries to pull the woman to safety but loses her grip, and the woman falls.

Distraught over her failure to save the mother, Renee is examined by Dr. Qu (Derek Scott), who urges her to check into The Hidden Gate Spa with J. Street for some rest. When the two women arrive at the facility, they are greeted by Eugene and Sophie (Mark Burgess and Kate Greenhouse), the husband and wife who run The Hidden Gate. After reluctantly agreeing to turn over her weapons for safekeeping, Renee heads to the spa area for a soothing bath. Her peace of mind abruptly ends, however, when she thinks she sees a patron in the curtained bath next to hers being attacked by an Atavus. Renee dashes through the curtain only to find two spa attendants who subdue her. Renee returns to her room. In order to put her mind at ease, Street goes off to conduct a full reconnaissance of the facility.

Onboard the Taelon Mothership, Ronald Sandoval (Von Flores) shows Howlyn (Alan Van Sprang) a surveillance tape of Renee at the spa. He tells Howlyn that Renee is clearly at the breaking point, and the time is ripe for him to take her. To make things even easier, Sandoval shows Howlyn a device with which he can further weaken his intended victim: the Soma-Nega-Blocker, a sleep inducing machine that the spa patrons use.

Back at the spa, Renee is haunted by dreams of Howlyn, who tells her she'll never save humankind from the Atavus. She awakens in a cold sweat, convinced she is having a complete breakdown. Meanwhile, at Eugene's desk, Street finds video monitors bdisplaying images from virtually every room in the spa. As she snoops further, Street spots Sophie leading a female patron into an Atavus hive.

Street is startled when she encounters Eugene. He tells her that his wife has been undergoing a personality change. Suspecting that Sophie is an Atavus hybrid, Street asks Eugene to take her to recover Renee's weapons, but when Eugene opens the safe where they had been stored, the weapons are gone.

Groggy after her dream encounter with Howlyn, Renee tries to find Street, but instead encounters Sophie, who persuades her to relax in a tub in the spa's luxury treatment area. Sophie then contacts Howlyn. A few minutes later, Renee hears someone breaking into the treatment area. When Renee realizes it's Howlyn, she flees leaving the bath's faucet running. Howlyn confronts her, unaware he is standing in a pool of water. Renee quickly pulls a hair dryer from under a nearby towel and tosses it into the pool. Electrocuted, Howlyn falls to the floor unconscious, and Renee flees.

Intent on destroying the Atavus hybrid chamber, Street asks Eugene to go the basement and turn up the facility's boiler to its maximum. In the basement, Eugene sees Sophie chasing Renee with an energy knife. He shoots her with a nail gun, but she recovers and stabs him to death. Sophie continues to pursue Renee, catching up with her on a guest-room balcony. The two women struggle and tumble over the railing. Sophie falls to her death, but Street arrives in time to pull Renee to safety. With the boiler about to blow, they flee the building. Meanwhile, onboard the Mothership, Sandoval engages an emergency portal to whisk Howlyn to safety.
