Bonanza (1959) : 1x14

This episode begins with Adam defending the honor of Sue Ellen Terry in a duel. No one gets shot because the other man misses Adam and Adam generously shoots in the air to end the duel. Sue Ellen lives with her sister, who seems nice but turns out to be fairly evil, consumed with jealousy because she's getting older and her sister is a young beauty. When Adam drops Sue Ellen off after a date one night, half way through this episode, someone shoots her dead, and Adam becomes a suspect and is thrown in jail. When the sheriff suggests that Adam escape, he does it, but when he walks out, someone tries to shoot him. He chases after them but doesn't find them, and soon after hears Sue Ellen's sister scream. He runs up the stairs to find her dead, and of course, is then suspected of that murder as well. Of course, his family helps him during the last half hour, and it all turns out that someone we should not have suspected did all the murders, but that he actually wasn't trying to hit
