Plot[]

Part 1: "Ihea 'oe i ka wa a ka ua e loku ana?"[]

McGarrett and the task force track down a suspect who might be connected to the stolen list of undercover CIA agents. When the suspect gets away, the task force run into Thomas Magnum and his partner, Higgins and discover that they are looking for the same suspect for a client they are looking after. McGarrett reluctantly begins working with Magnum and his team to try to find the stolen list. Meanwhile, Tani reaches out to Adam concerning about his wellbeing only for Adam to flee Hawaii. Also, after getting advice from Higgins, Tani asks Junior out on a date only to get kidnapped by thugs.

Part 2: "Desperate Measures"[]

When Hong, a man that Magnum and Higgins are monitoring for a client, gets shot and killed and his killer escapes, the team from Hawaii Five-0 gets involved. Magnum, Higgins, TC and Rick assist as the group recovers a secret list of CIA double-agents. Soon after, Junior Reigns is kidnapped as leverage for the criminals to get the list back, leading to Magnum's team helping Tani Rey and Quinn Liu in a search-and-rescue mission.

Production[]

Before the crossover, Hawaii Five-0 characters had crossed over to Magnum P.I., such as Kamekona (Taylor Wily), Duke (Dennis Chun), Noelani (Kimee Balmilero), Flippa (Shawn Mokuahi Garnett) and P.I. Harry Brown (William Forsythe).^[4] The showrunner for both shows, Peter M. Lenkov, had wanted to include MacGyver (also showrunned by Lenkov) in the crossover, but eventually it was decided to just do a Hawaii Five-0 and Magnum P.I. crossover.^[5]
