Snapped

Native South Korean identical twin sisters overcame a difficult childhood to become co-valedictorians in high school. They both seemed headed for success until, at 23, one of them developed a gambling habit and began stealing and forging checks to pay her debts. When she needed help, her twin sister took her in, even though they had a love/hate relationship. Their sibling rivalry would eventually escalate to burglary, identity theft and murder.
