When people are afraid of you... you can do anything. Remember that.

Twins Ronnie and Reggie Kray are raised in east London, under the influence of their hateful but doting mother Violet. As they grow up, Ronnie's violent nature takes over, and Reggie follows his brother's lead. The two become notorious crime lords who rule over the East End club scene. But at the height of their power, the brothers veer into different lives, giving the older crime bosses a chance to reclaim what the Krays took from them.
