“The Day It All Came Together” Plot – Hannah (guest star Jordana Brewster), 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. Also, Magnum makes an earnest proposition to Higgins for her to become his private investigations partner.

The Season 1 Plot:

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 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.
