A Quiet Place Part II (2020)

In the small town of Millbrook, New York, the Abbott family — parents Evelyn and Lee, daughter Regan, who is deaf, and sons Marcus and Beau — attend a Little League baseball game. A meteor-like object is seen hurtling toward Earth. Soon after, hostile alien creatures emerge and begin attacking. The blind creatures possess armored skin, incredible speed and strength, and an acute sense of hearing, attacking anything that makes noise.

Over a year later, the aliens have killed much of Earth's population, including Lee and Beau. Regan discovers that high-frequency audio disrupts the aliens and modifies her cochlear implant to emit the signal via a handheld microphone. With their home destroyed, the surviving Abbotts set out in search of other survivors. While entering a fenced-off area, Evelyn accidentally activates a sound alarm. Marcus steps into a bear trap and screams, attracting an alien. Regan and Evelyn kill it, free Marcus, and take shelter in an abandoned steel foundry.

They encounter Emmett, a former friend who has lost his family and lives alone in a soundproof bunker. He reluctantly allows them to stay but refuses further help. Marcus hears the song "Beyond the Sea" playing repeatedly on a radio station. Regan interprets the signal as a message from survivors living on the nearby Norwalk Islands. She theorizes that if she can reach the island's radio tower, she can broadcast the high-frequency signal as a weapon. Regan sets out alone but is attacked by an alien. Emmett rescues her and eventually agrees to help complete her mission.

Evelyn leaves the foundry to retrieve medical supplies, leaving Marcus and the baby behind. While exploring, Marcus finds the decaying body of Emmett's wife. Startled, he makes noise, drawing an alien. He hides with the baby inside an air-tight compartment, risking suffocation.

Emmett and Regan reach a marina, where they are ambushed by hostile looters. Emmett intentionally draws aliens to the scene, which kill the attackers. One creature drowns, revealing that the aliens cannot swim. Emmett and Regan escape in a boat and reach the island, where a small colony of survivors lives in relative safety. The colony's leader explains that when the U.S. government discovered the creatures could not swim, the National Guard attempted evacuations to the islands. However, chaos during boarding attracted the aliens, and only two of twelve boats made it.

Meanwhile, Evelyn returns to the foundry and rescues Marcus and the baby. The family hides in the bunker as an alien enters the facility. The next day, an alien reaches the island on a drifting boat and attacks the colonists, killing the leader. Regan and Emmett flee to the island's radio station. Regan transmits the high-frequency signal over the radio, incapacitating the alien, then kills it using a metal rod.

Back at the foundry, Marcus hears the broadcast and plays the signal through a portable radio, weakening the alien inside before shooting it. Regan leaves her cochlear implant connected to the radio station microphone, enabling the signal to be broadcast for use by other survivors.
