Magnum P.I. Season 4 premiere Friday, Oct. 1 at 9 p.m. ET on CBS. Naturally, Jay Hernandez is back as private investigator Thomas Magnum, along with Zachary Knighton as Orville “Rick” Wright, Stephen Hill as Theodore “TC” Calvin, Tim Kang as Detective Gordon Katsumoto, and Amy Hill as Kumu. 

Perdita Weeks will also return as ex-MI6 agent Juliet Higgins. After the season 3 finale, some Magnum P.I. may have feared that Weeks was leaving the show for good. In that episode, her character decided to travel to Africa for six months with her boyfriend Ethan Shah (Jay Ali) while he worked with Doctors Without Borders. But Weeks will appear in season 4.

The season 4 premiere, which is titled “Island Vibes,” sees Magnum diving into a new case while also juggling a new relationship. Meanwhile, Higgins, who is still away from Hawaii, she gets pulled into a situation with her previous employer. Images from the premiere show her working at her laptop in what looks like an African village and beating up bad guys while wearing a mask. 

Here’s the full episode description from CBS: 

As Magnum tries to keep his new relationship a secret and handles cases solo while Higgins is away, he is tasked with finding a single mom being hunted by two very dangerous gangs. Also, while Higgins is abroad with Ethan, a misstep forces her to assist an old employer, and Rick gets some bad, but also very, very good news, on the fourth season premiere of Magnum P.I.
