Mudeomgaui Gaedeul

In the American West of the 1900s, Richard, who had been hiding his criminal past while making a life for himself on a rural ranch,
discovers Theo, a young man left for dead in the desert. Under normal circumstances, he would have walked away, but something about Theo’s plight tugged at his heart, so he took him in. Richard begins to realize that Theo, who seems to be hiding a secret, is just like himself... As their shared sense of suffering turns into an unexpected attraction, and the moment they realize they feel the same way, the two are forced to confront a truth about their past that they never wanted to know.
