Director John Singleton teams with screenwriter Karen Croner to detail the quest of an ACLU lawyer in seeking to expose a rash of small-town Texas drug convictions as corrupt and racially motivated. Adapted from author Nate Blakeslee's book Tulia: Race, Cocaine, and Corruption in a Small Texas Town, Tulia features headlining performances from former Monster's Ball co-stars Billy Bob Thornton and Halle Berry. ~ Jason Buchanan, All Movie Guide
