Locked In is a 2023 psychological thriller film directed by Nour Wazzi and written by Rowan Joffé.

Katherine, a former TV star, wakes up in the hospital after a severe accident that has left her with locked-in syndrome, where she is completely paralyzed and cannot communicate.

Dr. Robert Lawrence, the family doctor, becomes involved in their lives and starts an affair with Lina, who's struggling with the lack of fulfillment and autonomy in her isolated life.

On the water, Robert deliberately capsizes the boat, and pulls Jamie deep underwater until he drowns.

As Katherine gradually recovers, Nicky teaches her to communicate by responding to letters of the alphabet by blinking.

In a more detailed flashback from the night of the accident, we see Katherine shoot Robert's tire as he tries to run Lina down, having second thoughts about hurting her.

Lina tricks Robert and injects him with a lethal drug he has prepared for Katherine, but it is not strong enough to kill him.

It is the feature length debut of director Nour Wazzi who worked from a script by Rowan Joffé.
