Man & Wife, Cop & Crook (2008)

Marion is a high-powered cop. Luc, her husband, hates her taking risks, so she tells him she's a lawyer. Luc is a gentleman thief. His wife has been on his tail for three years so he tells her he's in real estate. With two kids, they are each blissfully ignorant of each other's double life. Until one day, when a corrupt cop threatens to arrest them both (him for theft, her for complicity), unless they pull off the heist of the century and hand him the swag. Of course, Marion and Luc can't let him get away with it.
