Hawaii squadra cinque zero: Journey Out of Limbo

SINOSSI

To the horror of workers at a construction site, the truck of sand they are unloading contains Danny Williams in the back, unconscious and just moments away from having smothered to death. Danny awakens, but can't remember anything about how he got there. McGarrett grills the sand-truck driver, but eventually abandons him as a dead end. The only other way Danny could have gotten into the dump truck was to jump in from a height as the truck passed below him. Danny remembers he was going horseback riding on his day off, so the Five-O team heads out to a ranch that rents horses for pleasure rides. Eventually they find the body of the horse he was riding, shot multiple times and leaving a long trail of blood. That means Danny was fleeing from gunmen and made his leap as a last resort. But what did he see that made the gunmen chase him. The answer turns out to be a literal suicide bomber, the ranch owner, who is getting revenge on a Chinese visitor by having a bomb-laden boat (with mannequins at the helm, which is what Danny saw being loaded into a truck headed for the harbor) "steering" it by remote control straight into the man's yacht with the dignitaries aboard. (Presumably the thugs got paid in advance). McGarrett and the Five-O crew must race the clock to destroy the bombers' boat before it can complete the madman's mission.
