Exit Right (1970)

Jan Randall, whose brain is affected by inoperable cancer, is deeply afraid of being trapped inside. Refusing to take medications that would reduce her final days to a hospital bed, she moves into a tent in her backyard. Determined to give her one last gift, her husband John courageously takes her on a trip around the world—oon foot, in their own hometown—for what is truly the trip of a lifetime.
