The estate's "majordomo" is Juliet Higgins (Weeks), a beautiful and commandingly rejected MI:6 agent who keeps Magnum in line. When Magnum needs help with a job, he turns to his trusted buddies and surviving fellow inmates, helicopter pilot Theodore "TC" Calvin (Hill) and Orville "Rick" Wright (Knighton), a former Marine doorman who now runs a nightclub . Magnum has regular run-ins with police detective Gordon Katsumoto (Kang), and the two are more alike than they care to admit. The unofficial 'housemother' and Robin's Nest cultural curator, Teuila 'Kumu' Tuileta (Hill) is also one of Magnum's biggest fans.

The fifth season of Magnum, P.I., which airs on Sunday nights, averages 0.27 in the 18-49 demographic and 3.35 million viewers. Compared to season four (which aired on CBS), that's a 35% drop in the demo and a 36% drop in viewers in the live+same day ratings (including DVR playback until 3am). It has performed moderately in the traditional ratings.
Last year, CBS canceled the reboot series after four seasons because the network and the series' co-producing studio, Universal Television (owned by NBC-Universal), could not reach a financial agreement for a fifth season. As traditional ratings have fallen, networks are less willing to spend so much money on series they don't own.
NBC revived the series for twenty episodes. It was initially reported that they would be split between seasons five and six. It was later confirmed that they would all be part of a fifth season. Ten episodes aired during the 2022-23 season and the remaining ten episodes will air during the upcoming 2023-24 season.
The cast's options expire on June 30, and NBC has opted not to renew them. The network could have renewed them and then had the next year to decide if they wanted a sixth season, putting the cast on hold for a year. With the uncertainty of the ongoing writers' strike, it has been decided to end the series.
The 20-episode fifth season will conclude in 2024.
