The Season 5 Plot, Courtesy of NBC:

Magnum P.I. is a modern take on the classic series centering on Thomas Magnum, a decorated former Navy SEAL who, upon returning home from Afghanistan, repurposes his military skills to become a private investigator. 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 backup 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.

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!
