hree couples learn some difficult lessons about the cost of infidelity in this drama from Mexico. Mujeres Infieles offers three stories of spouses who stray, each from a different point in the couple's relationship -- the first concerns two people about to be wed, the second looks at a couple who have been married for several years, and the last follows a man and woman who are only going through the motions after decades together. In each story, looking for adventure outside of a committed relationship brings passion, excitement -- and tragic consequences.
