The Beast Episode 1.06 Hothead

There's nothing more dangerous than an FBI agent who's gone rogue, and Frank Oland may be one of them. Barker, who trained with Oland at Quantico, sends Ellis undercover at the security company where Oland works to keep an eye on him. Ellis poses as an unpredictable and sometimes violent U.S. Marine to get close to Oland. The case gets even more complex when Barker searches for Oland's former girlfriend--who just happens to be one of Barker's former girlfriends, too.
