Sharareh

Even though a guy already has two wives, he gets obsessed with one of his wives' sisters, Sharareh. To get with her, he spreads a rumor that he's dead, changes his look, and tries to put the moves on her in disguise. But when she shuts him down, he threatens the guy she's actually seeing, which still gets him nowhere until his whole scheme is exposed. He finally regrets what he did, and in the end, Sharareh marries the guy she loves.
