Dick Powell's Zane Grey Theatre (1956)

S3E9 Pressure Point

In the quiet town of Top Rock, Jess Clark loses his sight when his horse stumbles into a gopher hole and injures itself. Unbeknownst to the townsfolk, the peace is shattered when Lew Banning escapes from prison, seeking vengeance for his brother's death at Clark's hands—blindness is no deterrent for Banning's thirst for revenge. The townspeople, wary of gunfighters, find themselves caught in a dangerous conflict as old rivalries resurface.
