Three seemingly ordinary people are recruited to make a hit on a mob boss from Chicago visiting Hawaii. The hit is done with precision. The killers are equipped with firearms with plastic coverings that prevent shell casings from being left for evidence, for example. Also, the three participants, in effect, provide alibis for each other. Five-O initially thinks this is a professional hit until its probe begins to uncover the truth. McGarrett & Co. must figure out why these three people were so desperate they could be blackmailed into performing a murder. Second, Five-O must figure out what the ultimate goal of the caper is.
