Bree [Nora-Jane Noone] walks into the bright, sunlit expanse of the Ketea Aquatic Center for a private moment of relief, a quiet backdrop for a sisterly bond that has survived more storms than most. Her sister, Jonna [Alexandra Park], is right there with her, a recovering drug addict who has just celebrated three months clean. The two move through the chlorine-scented air with a mix of nerves and familiarity, the pool’s Olympic-sized blue stretching out like a promise and a test all at once. The pool’s manager, McGradey [Tobin Bell], keeps a vigilant eye on the late-day crowd and, after catching Clara, an ex-convict on parole who works as a janitor, attempting to steal from the lost and found, he fires her and asks the customers to start leaving as the holiday closure looms.

The moment shifts from routine to crisis when Bree discovers her engagement ring missing while they’re packing up. The two dive into the deep end, chasing a glimmer of ring chrome in the water’s mirrored bottom, only to find the ring lodged in a metal grille. The two dive deeper, determined to recover it, while McGradey, unaware that the sisters have slipped into the pool’s deeper half, seals the fiberglass cover and steps away, thinking the night is over.

What follows is a whirl of fear, desperation, and mother-to-daughter-like resilience. The sisters push and twist, trying to lift the cover, chisel a way through the small holes, or simply break free from the trap that closes around them. No escape works, and the pair are left with a single fragile option that feels almost too small to matter: the small hole they can barely fit through. Bree’s confession lands like a weight in the water—she had thrown the ring into the pool in a moment of envy over Bree’s apparently flawless success and engagement. Calm gives way to anger, then to raw truth as Bree opens up about their shared past, their abusive father, and the fire that killed him after years of harm. Bree reveals her diabetes and the urgent need for insulin, a detail that underscores the real, daily stakes of their survival.

Clara’s arc takes a dangerous turn as she plans to leave with Bree’s cash, smartphone, and credit card. She taunts Bree with a password and a PIN, forcing Bree to reveal them in exchange for their freedom. But the night grows darker; Clara turns off the water heater, leaving the sisters trapped for hours that blur into an eerie limbo. When Clara returns to taunt them again, Jonna’s anger blooms into an act of defiance: she uses a shard of tile to stab Clara in the ear by pressing it against the pool cover’s hole. The injury escalates the tension as Clara retaliates by starting the automatic pool cleaning system, a choking wave of chlorine that threatens to sweep Bree and Jonna into its deadly, unseen current. She pulls back the lever not long after, realizing the catastrophic consequences that could follow.

As the dawn light threads through the pool area, Bree’s truth about their father’s abuse surfaces with quiet, painful clarity. She had once called him a monster in defense, placing the weight of their past squarely on the shoulders of their family history. The revelation reframes everything: the ring’s disappearance, the fear, the fight for breath, and the emotional toll of their shared history. Clara returns, physically present but emotionally distant, realizing the error of her actions and struggling to regain access to the passcode that would unlock the pool’s cover. She tells the sisters they’re on their own and slips away again, leaving behind a cloud of consequences.

With the air turning cooler and the water cooling their nerves, Bree’s strength falters. Yet in a moment that shifts the balance of power, Jonna manages to rip the metal grill free from the pool’s bottom—an act Bree had tried and failed to accomplish before. The pool cover finally bursts open under their combined effort, and the siblings scramble out of the water to safety. The immediacy of life becomes a rhythm: Jonna administers Bree’s insulin shot, a small but crucial act that anchors Bree’s fragile stability as they move toward the surface of the night.

Clara’s return—armed with a gun and the memory of her own past mistakes—threatens a final, desperate climax. But a complex moment of mercy overtakes violence; instead of fatal outcomes, Clara places the gun down, returning their belongings and letting the sisters reassemble what they can. Jonna calls the police, and Clara, faced with the consequences of her choices, waits for the system to take its course. In a quiet, almost conciliatory gesture, she steps back and allows them to escape with their dignity intact, if not their freedom from fear. Paramedics arrive to tend to Bree, while Jonna tenderly retrieves Bree’s engagement ring, the ring a symbol of the life Bree hoped to begin with.

As the two stand in the corridor that separates danger from safety, the moment crystallizes into a shared memory of survival. The injury, the fear, and the stubborn thread of forgiveness loop back to a line Bree once spoke, reimagined through Jonna’s act of compassion: we killed the monster. The sentiment—a categorically human response to monstrous fear—resonates as the sisters realize they have not merely escaped a physical trap, but also confronted the deeper, more insidious monster in their world: the echoes of abuse and the possibility of choosing a new path together.

Notes on who’s who in the moment:

  • Bree [Nora-Jane Noone] is a diabetic with a past shadowed by family violence, clinging to hope through her engagement and a glimmer of sisterly solidarity.
  • Jonna [Alexandra Park] is her younger, protective sister, newly sober and courageous, whose acts of courage become the hinge on which their escape turns.
  • Clara [Diane Farr] is the enforcer of the night’s dark bargains, a figure of danger who is ultimately tempered by a moment of empathy.
  • McGradey [Tobin Bell] is the pool’s manager, whose decisions ripple through the night’s events.
  • Detective Zimmerman [Donald Prince] is the law figure who will emerge as the Sisters face the consequences of the choices made within these hours.

“We killed the monster,” as Jonna tells Bree in a final, quiet declaration, signaling that forgiveness has broken the strongest hold of the night and letting them move forward with a fragile, stubborn hope.
