Magnum P.I. begins its fourth season with Hawaii’s favorite detective Thomas Magnum taking on intriguing and exciting new cases with his partner Juliet Higgins, whose second job is to keep Magnum in line, with the help of her two Dobermans. This season, while Higgins returns to Oahu with an unexpected secret mission from her old employers at MI-6, Magnum begins a new secret romance with a police colleague of Katsumoto’s. Always 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, the owner of La Mariana’s, the coolest bar in town – both whose lives get turned upside down by new and unexpected relationships. With the keys to a 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!
