Seraphina Angela, infamously known as 'The Ruby Cadillac' is the original heiress to the throne of her father's mafia, which is partnered with the leading king & queen of the Italian mafia; Carter Fenix and Delilah Fiora Fenix. Seraphina isn't a regular assassin, she fulfilled her mom's legacy in becoming a ruthless killer by a special talent she possesses & uses to her advantage; dance fighting. She doesn't show weakness and wears blood like perfume, rather elegantly. On her path to becoming a Donna, Seraphina gets an order from the higher authority to eliminate the heir to the Spanish throne, nobody other than 'The Death Rider.' Vincent Salvador is the man behind the mask, better known as the 'The Death Rider'. He has his eyes set on becoming the king of the underworld but as of now, he is the heir to the Spanish mafia throne. Nobody knows Vincent's ways of becoming a king, the lengths he'd go to, and the sacrifices he'd make. He is the leader of the undefeated underworld gang called 'The red saint's masquerade'. With a mission to conquer the Italian mafia, his plan is to make Seraphina his sacrifice so he could embellish his authority. With her target being set upon assassinating Vincent, will she end up uprooting many secrets held in her life? Would Vincent be able to give up the woman that soon becomes the shining star that lights up every dark corner of life? Is the dancer in the dark going to succeed and become everything she has ever wanted to be or will he become everything she has ever wanted?
