However, after weeks of spying on the lovebirds, Simon finds himself falling for the dame. When a chance meeting sparks a torrid affair, she convinces the honest lawman to plot the untimely murder of her criminal mate. But questions soon loom in Simon's mind: how long before she takes another lover and how long before they plot his own murder?
