After a tourist pair accidentally runs over mister O'Connell, who ran burning out of a sugar cane field and dies from cardiac arrest, Steve immediately suspects his last and frequent phone contact: haughty therapist Dr. Olivia Victor, who plays a cat and mouse game, faking his patient file was accidentally deleted and tricking him to violate a restraining order. O'Connell hired private detective, who is also killed. Steve again blames her and wants to prevent her leaving Hawaii even before the team finds out her actual business plan. Catherine teams up with intelligence officer Chris Channing, who got suspended due to her illegal search for Steve's mother Doris, who is told to hide as the presumed dead Colombian hitman 'Mangosta', once hired to kill her, is signaled alive on the island, leading to grim spy style confrontations.
