A serial killer is at large in Hawaii. Killing women one after another.
To Steve and Danny's luck, they run into the trouble making twins, Marni and Fran--literally--who are also police officers.
As the killer becomes more and more dangerous, Steve doesn't want Marni or Fran on the case, but the twins soon become involved, and are next on the killer's list. Fights happen, tears fall, words are regretted, but in the end, how will things turn out?
