Controversial methods are applied by FBI agent Charles Barker in his attempts to bring offenders to justice, which often border on his uninitiated partner, Ellis Dove. Over the course of the season, fellow FBI agents investigate Barker for misconduct. Dove's loyalty for his partner will be contested when internal affairs agent Ray Beaumont (Larry Gilliard) approaches him to obtain information. Afterwards, Dove learns of secrets in Barker's past.
