Five-O is protecting Billy Madrid, lieutenant to a crime boss who will testify in an upcoming trial. McGarrett is wounded when a sniper shoots at Five-O officers escorting Madrid, an indication that the crime boss wants Madrid dead. But when the trial actually starts, Madrid tells a different story -- that McGarrett forced his testimony. Now, McGarrett & Co. must find a way to recoup or else the crime boss will go free.
