What is Netflix's Locked In about?

The film follows former actor Katherine, who suffers from locked-in syndrome after being hit by a car, leaving her nurse Nicky to figure out what happened to her.

The official Netflix synopsis reads: "Katherine, a former Hollywood actor, wakes up in the hospital unable to move. She's been hit by a car and suffers from locked-in syndrome — her eyes are the only thing she's able to move. Through her nurse, Nicky, we find out what's led to Katherine's hospitalization. Katherine, communicating with her via letter board, blinks when Nicky reads the correct letter: She claims there's been a murder.

"Through flashbacks, we see snapshots of Katherine's life just after she adopts her late best friend's daughter, Lina. Lina idolizes Katherine and quickly becomes close with her chronically ill son, Jamie. Later, Lina and Jamie get married — much to Katherine's dismay, as Jamie is the heir to his late father's manor, where they all live. As Lina and Katherine's relationship deteriorates, Lina bonds with Jamie’s doctor, Robert, and tragedies befall Katherine's family."
