Time Out says
Boy (Kutcher) meets girl (Heigl); boy is an assassin for the CIA (what else would he be?) and retires early in the name of love. Three years later, the now-married couple have settled into domestic bliss...surrounded by killers out to collect a spook-sponsored bounty on the former agent’s head. Borrowing from romps ranging from Charade to the suburban mayhem of Mr. & Mrs. Smith, this high-concept hokum might have worked with an actual leading man; for someone so classically handsome, Kutcher is surprisingly anticharismatic as a star. A smarmy grin and looking good while shirtless does not equal screen presence, dude.
