12 Feet Deep

Bree and Jonna head to the Ketea Aquatic Center for a late-day swim as the Olympic-sized pool winds down for a holiday closure. The quiet, isolated setting heightens the tension between them. Their night ahead will reveal secrets and test their bond.

McGradey fires Clara after catching her attempting to steal from the lost and found and orders everyone to leave. The pool closes for the holiday, leaving Bree and Jonna to face the night alone. Clara’s sudden dismissal removes a potential ally from their desperate situation.

Bree discovers her engagement ring is missing as they pack up. The ring is stuck in a metal grille at the pool’s bottom and the sisters dive in to retrieve it. Unbeknownst to them, the pool cover is engaged and the pool is effectively closed for the night.

Terrified, Bree and Jonna realize they cannot push the heavy pool cover up or break through it. They search for a way out through a small hole, but the space is limited and the air grows thin. The fear of being trapped becomes overwhelming.

Jonna admits she threw the ring into the pool out of jealousy, and Bree reveals the truth about their abusive father and the fire that killed him. Bree also confesses she is diabetic and needs insulin to avoid a coma. The revelations deepen their emotional wounds but strengthen their resolve to survive.

Clara, preparing to leave, sees the sisters and steals Bree’s cash, smartphone, and credit card, demanding Bree’s password and PIN. She turns off the water heater and leaves them trapped for the entire night. The sisters wake to an ominous sense of isolation and danger.

Next morning, Clara taunts them again. In anger, Jonna uses a shard of tile to stab Clara in the ear by pressing it against a small hole. Clara retaliates by turning on the pool’s automatic cleaning system, flooding the pool with chlorine, but she stops before causing serious harm and departs.

Bree confesses to Jonna that during the accident that killed their father, she deliberately prevented him from escaping, calling him a monster for sexually abusing them. The admission adds guilt but also a shared resolve to move forward. Bree also reiterates her need for insulin, reminding them of their fragile health.

Clara returns after reconsidering her course and tries to force open the pool cover, only to find her passcode no longer works. She tells the sisters they are on their own and leaves again, leaving them to navigate a dangerous situation without help. The shift marks the end of Clara’s control over them for now.

Bree grows weak while Jonna finally rips the metal grill from the pool bottom and smashes the pool cover. The sisters seize their chance and scramble to the surface, escaping the claustrophobic trap. Breathing the open air, they begin to process what they’ve endured.

Jonna administers Bree’s insulin shot once they reach safety, stabilizing Bree’s condition after the prolonged exposure. The moment marks a shift from survival to health as they process their ordeal. They steel themselves for whatever comes next.

Clara returns with a gun, threatening to kill the sisters rather than face prison again. Yet something in their forgiveness moves her to lower the weapon and return their belongings. Clara’s change hints at a deeper transformation sparked by the sisters’ mercy.

Paramedics arrive to tend to Bree, and Jonna returns Bree’s engagement ring which Clara had taken. The sisters’ line about killing the monster echoes as they acknowledge their father’s abuse and the harm Clara nearly embodied. The night ends with a fragile sense of closure and the first steps toward healing.
