A vision of a predawn escape by boat from Denmark seems confusing to Journalist Natalie Seachrist. She has no idea how scenes apparently from a World War II movie will impact her modern life in Hawai’i. Soon, she and boyfriend, private investigator Keoni Hewitt, move into the Lanikai cottage she recently inherited. The warm welcome they receive from Miriam Didión and her housemates sets an ideal tone for life in the seaside neighborhood. As Natalie throws Keoni a birthday party everybody, including Natalie’s feline companion Miss Una, have become fast friends.
Abruptly, everyone’s life changes when a body is found at Miriam’s home. Eerily, the murder parallels another of Natalie’s visions of a scuba diver garroting a woman by moonlight. Natalie reveals the murderous vision to Keoni’s former partner, Honolulu Police Detective John Dias. Discovery of a suspect’s body on Diamond Head Beach suggests resolution of the crime and Natalie and her new friends relax. But a day of playing tourist devolves and Natalie and her friends are suddenly in the cross hairs of a dangerous adversary.
