Diamond in the Rough

This is a story based on the movie "The Town" and the book "The prince of thieves" by Chuck Berry. This is my own adaption, a fan fiction. I don't own any of the characters in the story unless clearly stated.

The Town's resident bad boy is finally out after spending nine long years in a state correctional facility and is ready to cause chaos, which is long overdue.
Jem Coughlin, a violent individual wants money and lots of it. He and his three friends do what they do best. Rob and steal.
However, after the first job Jem meets someone from his past and is literally in shock. How will he cope with an ex-girlfriend from high school showing up?

Meanwhile, Jem's buddy Doug is mapping out jobs and starts falling for one of the victims.

Will their love interests change them or will they be sent back to Walpole?
