An uneasy friendship turns into a dangerous game when the love of a woman is on the line.
Tom Breckinridge has been falling in love with Diana Marshall for the past year, but just when has decided to come to the point, a rival has come out of the woodwork: Reginald Popplewell, a childhood playmate of Diana's, and now heir to a viscountcy! Diana's father much prefers Reginald, but Tom believes Reginald has something to hide.
When Tom shares his doubts with Diana, however, she won't hear a word against "dear Reggie" and goes so far as to wring a pledge from Tom that he will become Reginald's friend. Fulfilling this promise, Tom quickly discovers just how risky it can be to befriend a con man, and is forced to decide to exactly what lengths he is willing to go to win Diana.
