Undercover Cop

Bored so I'm randomly making a story that is user driven, no pun intended ok so you, the user, can be any gender and style that you want for this story. So the story goes that you used to be a respected cop who sworn to protect when behind the scenes your superiors where corrupted and greedy into illegal activities. You were sent to go deep into the the underground world of street racing to dig some dirt up on the local crews when in reality they just wanted the spoils of your wins and information to gain an upperhand in their hidden corruption. You become suspicious of your fellow officers the longer your undercover acting as a fellow street racer. How will this play out in your story? I hope you have fun and enjoy my random story haha
