Magnum P.I. (Seasons 1–5)

Magnum P.I. (2018) is a CBS crime-adventure series you can watch online on iFILM. Jay Hernandez plays Thomas Magnum, a decorated former Navy SEAL who trades the Afghan desert for the Hawaiian sun and sets up shop as a private investigator — taking on the cases that slip through official cracks.

He is rarely alone. Fellow vets T.C. Calvin (Stephen Hill) and Rick Wright (Zachary Knighton) have his back in the field. The estate he calls home is run by Juliet Higgins, a former MI6 operative played by Perdita Weeks, whose clipped professionalism collides with Magnum's improvised instincts in every episode. Their dynamic — half rivalry, half grudging trust — gives the show its spine.

The series does not try to be gritty. It leans into warm-weather energy, sharp banter and the kind of action that moves fast enough to keep you from checking the time. A confident update of the classic 1980s original. Stream all seasons of Magnum P.I. online on iFILM.
