Leopold Kroner, a former employee of Colby Enterprises, was released after serving five years in prison on corruption charges. Andrew Colby claimed that Krona had threatened him, so he hired lawyer Bob Reagan as a secret bodyguard. As expected, Krona appeared in Colby's room with a gun, and Reagan killed him. Then, Reagan, who insisted on romantic Colby's secretary Noel, began to suspect that he had been used.
