The Rebels(1968)

Original title: المتمردون

A sick doctor is admitted to an isolated sanatorium located in the middle of a desolate desert. As a patient, he becomes aware of the discrepancy that exists between the conditions of the privileged patients, who are well-treated, and the poor ones, who particularly suffer from a lack of water. With the help of the doctor, the poor patients rebel and undertake to restore justice and order in the hospital.
