Rosario is a beautiful teenage schoolgirl who lives in a dangerous Colombian town surrounded by sicarios, drug cartels, and prostitution. At a young age, Rosario was raped twice by gang members and constantly harassed by school bullies, which made her seek revenge when she had had enough: she used a pair of scissors to kill her tormentors, which earned her the nickname "Rosario Tijeras" and a dark reputation. Years later, as a grown woman and a cold, feared sicaria, Rosario runs into Antonio, a wealthy businessman she had met during a school trip, and he remembers her as "the girl with the scissors". Rosario falls in love with Antonio and his heartbreaker best friend Emilio, but her enemies return to even the score with her.
