Hannah, Magnum's ex and the fugitive responsible for him and his SEAL team brothers being POWs for years, shows up at his home with a gunshot wound, and wanting his help to find her missing CIA father whose life is in danger.

A charming rogue, an American hero and a die-hard Detroit Tigers fan, Magnum lives in a guest cottage on Robin's Nest, the luxurious estate where he works as a security consultant to supplement his P.I. business.
The "majordomo" of the property is Juliet Higgins, a beautiful and commanding disavowed MI:6 agent whose second job is to keep Magnum in line, with the help of her two Dobermans.
When Magnum needs back-up on a job, he turns to his trusted buddies and fellow POW survivors, Theodore "TC" Calvin, a former Marine chopper pilot who runs Island Hoppers, a helicopter tour business, and Orville "Rick" Wright, a former Marine door-gunner-turned-impresario of Oahu's coolest nightclub and the most connected man on the island.
Suspicious of Magnum's casual attitude and presence at his crime scenes, Detective Gordon Katsumoto finds that he and Magnum are more alike than either of them care to admit. With keys to a vintage Ferrari in one hand, aviator sunglasses in the other, and an Old Düsseldorf longneck chilling in the fridge, Thomas Magnum is back on the case!
