The Pan Am crew rolls the dice in more ways than one in glamorous Monte Carlo: Kate and Maggie square off for the attentions of a handsome passenger, but things get more complicated when Kate learns the sexy stranger is involved in her next covert mission; and Dean gambles with his career when an attractive, wealthy woman on the flight tempts him -- and he later discovers who her flying companion is.

Ted asks Laura to help him make a woman from his past jealous; a dangerous mission puts Kate and Anderson in jeopardy; Maggie clashes with a congressman; Colette meets Dean's parents.
