However, they both share an alter-ego called the Black Rose, a notorious cat burglar who dresses in a black leotard, and steals from the rich to give to the poor - taking on a Robin Hood-style mission. Even with their antihero status, the Black Rose has created uneasiness and tension in the high society; therefore, an insurance detective investigates the crimes and tries to unmask the woman behind the cat mask.
