The Fugitive (1963)

Gerard tracks Kimble to a migrant community in South Texas where he finally captures the fugitive who attempts to flee by train. But a violent hurricane strikes the area and forces them to seek shelter in a fragile barn where most of the farm workers are gathered. But when Gerard is badly injured when the roof collapses on him, Kimble, to the astonishment of the workers, actually helps try to save the lieutenant by helping transport him to another building where the fugitive pleads for a blood doner to save Gerard's life whom has weakened by the loss of blood.
