The third season of MAGNUM P.I. returns with Magnum (Jay Hernandez) and Higgins (Perdita Weeks) working in sync as private investigating partners, just as she begins a new relationship with her doctor, the handsome Dr. Ethan Shah (Jay Ali). Rick (Zachary Knighton) continues to manage La Mariana, the hottest tiki bar on the Island along with his best pal and Island Hoppers boss, TC (Stephen Hill), while Magnum and Higgins tackle cases that include re-possessing a plane from a drug cartel, helping an MMA fighter being blackmailed into throwing a fight and weathering a hurricane inside La Mariana with two armed killers. 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!
