*Just a short explanation, it's under construction*
12 years ago, Seth Gecko killed a woman, it was a robbery gone south. Seth was a 16 year old boy, and now 12 years later, at the age of 28, he's doing good, he's the CEO of a very rich and powerful company. He's still the leader of the same gang, and he still remembers that night. He remembers the babies cries echoing from up the stairs, he remembers the lady's plead for him to leave the money for her baby, and he remembers her lifeless body dropping to the floor because of a bullet he shot.

What happens when he meets a 15 year old girl? And that 15 year old girl turns out to be the baby who's cries he heard when he shot her mother dead.
