Warner Bros. and Silver Pictures have acquired Jonathan Herman’s prison thriller spec script Conviction.

The story follows a bank robber who is serving five years in prison for a heist gone bad. He is approached by an FBI agent to set up his criminal protégé who is in the midst of another high-stakes heist.

It will follow in the footsteps of such legends as Heat and Donnie Brasco. Andrew Rona and Joel Silver will produce.
