Magnum P.I. is a modern take on the classic series centering on Thomas Magnum (Jay Hernandez), a decorated former Navy SEAL who, upon returning home from Afghanistan, repurposes his military skills to become a private investigator.
A charming rogue, Magnum lives in a guest cottage on Robin's Nest, the luxurious estate where he works as a security consultant to supplement his P.I. business. The “majordomo” of the property is Juliet Higgins (Patricia Weeks), a beautiful and commanding disavowed MI:6 agent whose second job is to keep Magnum in line, with the help of her two Dobermans.
