An underwater attack on Jesse involves an orange light; and an unexplained Air Force presence smacks of a cover-up to Larkin, who feuds with Underlay.

Russell questions the mysterious circumstances surrounding the shooting death of a fellow worker at Underlay's hands. Meanwhile, Larkin becomes suspicious of an old flame's motives after he invites her to visit his military base, Mariel begins to worry that she hasn't been a good mother to her children since the hurricane - and she also wonders what Father Scanlon's intentions are when he invites her to attend his church survivor's group.
