Penelope and Liam Knight return to Los Angeles from their honeymoon to work on a strange case. The detectives disagree from the beginning on how to approach the murders. Four of the dead people worked for the Beeker Star Ships Company. They interview the owner, Paul Beeker, who called them regarding a container break-in. One of his tanker ships, the Star Caroline II, was the target. After the interview, the police monitor the Beeker’s and their warehouses for possible illegal activity. They believe somehow either the Beeker’s or others are responsible for the deaths and the shipping of illegal products from Mexico. They’ve narrowed the products to high-tech, military grade drone parts. The plan to catch the drone thieves takes winding turns when Cathy, Jane Beeker’s sister, identifies with an extremist gang involved in the drones. The drone parts are hidden in one of many tanker containers. Finding the right container and criminals appear impossible. Subterfuge and bluff become necessary. The detectives don’t always hit their mark. Frustration mounts and causes more problems than solving the murder cases.
