With Jill having moved onto a career in car racing, Sabrina and Kelly refuse to accept a new Angel into the fold, until they learn that who Charlie has hired as Jill's replacement is Jill's little sister, Kris Munroe, who unknown to Jill at the time was actually in the police academy in San Francisco and not at college as Jill had believed. The first case Kris will be working on with the other Angels is told to them through a late telephone call from Charlie, who, on the behest of those holding him, tells them that he has been kidnapped while vacationing in Hawaii. The Angels and Bosley are to head to Waikiki to await further instruction. Upon their arrival on the island, they quickly learn directly from the horse's mouth that Charlie's kidnapper is Leilana Sako, who wants to hire them to get her husband, Billy Sako, out of prison. The Sakos are into gambling and smuggling which prevents Leilani from going through official channels, not only because of the legalities but because many would like to see Billy dead. The price of the Angels failing is Charlie's life. The Angels quickly learn that between the two, Billy is the easy-going carefree one, Leilani the ruthless tiger, but that they are madly in love with each other despite their differences. Leilani also tells them that Billy is in prison on a trumped up charge. Regardless, the Angels have to figure out how to deal with what will be an illegal act on their part to save Charlie's life. In the process, they discover that there is another faction that knows they are on the island and don't want them to succeed in their mission, probably the same people who put Billy in prison. The Angels also face the issue that they are trying to save someone who they've never seen and thus cannot identify.
