Killers (2010)

Trying to recover from a sudden break-up, Jen Kornfeldt believes she’ll never fall in love again. But when she reluctantly joins her parents on a trip to the French Riviera, Jen happens to meet the man of her dreams, the dashing, handsome Spencer Aimes. Three years later, her seemingly impossible wish has come true: she and Spencer are newlyweds living the ideal suburban life – that is, until the morning after Spencer’s 30th birthday when bullets start flying. Literally. It turns out Spencer never bothered to tell Jen he was once an international super-spy, and now Jen's perfect world has been turned upside down.
