裂痕 第四季 (2011)

The fourth season takes place two years after the Tobin case. Ellen has moved on with her life. Now an attorney at her old mentor's firm, she's content with her cases and colleagues. Deep down, however, she wants a bigger challenge. When she discovers her friend has been through a traumatic experience while working for High Star, a private security firm hired by the U.S. government to carry out special missions in Afghanistan, she suspects foul play and asks Patty for help. Patty knows that trying a case against High Star can make Ellen's career. Or ruin it. It was inspired by recent events and controversies surrounding Blackwater Security Consulting.
