A man wakes up in a village by the ocean. He can’t remember anything and is taken in by a woman or family. He encounters a wounded or sick child and heals him “magically”. The community becomes scared of him. At the end remembers that he came from another dimension to find his brother (who turns out was Jesus) but missed him by many, many years.
“The Next One” made in 1984 and starring Keir Dullea
