A maverick computer genius named Bobby Quinn is gunned down by a sniper while playing golf with his employer, Lawrence Martin, the head of a large conglomerate. Martin hires Mannix to find the plans for a revolutionary computer that Quinn designed that will be the size of a briefcase. What Martin doesn't tell Mannix is that he knows Quinn also left behind a letter with the plans that has damaging information against Martin -- and that Martin has taken steps to ensure that Mannix will never read the letter even if he locates the plans.
