In “O-Mouth,” the agents are dealing with the aftermath of a recent mission. Mike Warren, a new recruit at Graceland, is still adjusting to the high-stakes world of undercover work. The team’s relationships are tested as they navigate the dangerous and often morally ambiguous situations they find themselves in.

Mike’s work becomes even more challenging when he is tasked with training new recruit Randall, a gang member Mike sees as good-hearted. A tug of war between what is priority complicates the constant pressure of living double lives.

Guest-starring Devon Dassaw as Randall.
