I don't think this one ever got a release in the USA. It's got a great score, good action, and kind of a soap-opera plot, but the actors do a good job and production values and sets are top notch. Leonard Mann and Peter Martell play two young gunmen who share a tragic past; childhood friends, they were separated when Mann's father was killed by his mother's lover. He was spirited away by a faithful servant while his sister (the lovely Pilar Velazquez) remained to be raised by the two murderous lovers. Rafael (a brooding Martell), childhood friend and servant also remains, but is practically a prisoner of the household until he grows up and escapes, searching for the missing Sebastian. Complications ensue. This one has a bit more heart than most spaghetti westerns, and if you are a fan of the genre, you'll enjoy it. 8/10
