Since his wife's death, wealthy industrialist B.K. Doran has been living the high life: expensive clothes, fine meals, exotic travel, and a very attractive lawyer/companion, Leslie Ross. His son-in-law Edward Lewis is concerned about bad business decisions, including the purchase of an obsolete plant in South America. He's also convinced that Doran has misappropriated company funds as well, and threatens to expose him at the next stockholders' meeting. Doran tells Lewis that he plans to resign at the meeting but in reality, on the advice of Ross, he is setting up Lewis to take the fall but Lewis neither believes nor trusts Doran. Lewis consults Perry Mason,who warns him to make sure his evidence of wrongdoing is solid. When Doran is killed, however, Lewis is charged with murder after being seen throwing the weapon into a pond. Perry defends him.
