When Kate's fiancé calls from Paris to tell her he's in love with another woman, Kate determines to do anything to get him back. She even overcomes her fear of flying so she can chase him down in the romantic city of lights. Then, while airborne, the panicky Kate meets Luc, a somewhat sleazy character who just happens to be a thief -- and who secretly plants a stolen possession in her bag. Luc intends to retrieve the loot when they land; unfortunately a conman grabs the bag first, thwarting Luc's well-laid plans. Soon he and Kate are frantically scouring the beautiful French countryside in hopes of getting back her precious carry-on.
