Fifteen days have passed since the shooting of Agent Seigel, but the FBI is no closer to catching his killer. Without a case agent, Neal is stuck at his apartment under house arrest, trying in vain to distract himself from the nagging feeling that his connection to Curtis Hagen may be responsible for his new handler's untimely demise.
With cases piling up and the department in need of a few wins, Peter decides to resume the Caffrey-Burke partnership. It isn't long before their first case lands in their laps when a reformed bank robber pushes into the FBI offices to confess to a crime that he can't remember committing. The investigation soon leads the team to a psychiatrist who may be manipulating her former criminal patients into returning to their old ways.
Naturally, Neal's background presents the perfect way in with their suspect, but when the good doctor subjects Neal to an experimental drug treatment that puts him in a highly suggestible state, the con worries that he has given away the FBI's investigation. With no evidence linking the doctor to any wrong doing, the only way to take her down will be to embrace the effects of her truth serum and turn it to their advantage. However, Neal may wind up sharing a little more than he bargained for in the process.
