Blood on the Moon — Luke Short

Blood on the Moon is widely hailed as one of the first noir Westerns. Director Robert Wise (The Sound of Music, West Side Story) used deep shadows and murky landscapes to convey the ambiguity of right and wrong in a film Variety calls "a terse, tightly drawn Western packed with suspense wallop."

Even a hired gun will only accept so much blood money. When Jim Garry finds out his latest job is part of one big double cross, he swaps sides to save a family in peril. But now he's fighting against his own kind -- and they'll stop at nothing to take him down.
