The King Tutankhamun artifacts are on display in Honolulu, thanks to the efforts of art patron Alicia Warren. While the exhibit is open, however, a man rushes in and smashes a display case, stealing Tutankhamun's gold death mask. McGarrett quickly recovers the item, but then discovers that the recovered mask is a forgery that has been switched for the real mask. McGarrett determines that there are several suspects in the theft, including the curator of the museum where the exhibits were displayed - and Alicia Warren herself.
