Breakdown(1955)

Mr. Callew, a demanding businessman, is resting by the beach when he receives a telephone call from a recently discharged employee. The man is in tears, but the unyielding Callew shows no sympathy, and hangs up on him. Later, when Callew starts to drive home, his car runs off the road at a construction site. When he comes to, Callew is paralyzed. Several persons come by, but he is unable to communicate with them, so they think he is dead. Fully aware of his predicament, he becomes increasingly terrified.
