After five (or six) years of vanilla-wedded bliss, ordinary suburbanites John and Jane Smith are stuck in a huge rut. Unbeknownst to each other, they are both coolly lethal, highly-paid assassins working for rival organisations. When they discover they're each other's next target, their secret lives collide in a spicy, explosive mix of wicked comedy, pent-up passion, nonstop action and high-tech weaponry.
Ann and David Smith are a happily married couple living in New York. One morning, Ann asks David if he had to do it over again, would he marry her? To her shock, he answers he wouldn't. Later that day, they both separately find out that, due to a complication when they married three years ago, they are in fact not legally married. Ann does not mention this to David, and thinks he will remarry her that very night after he takes her out to a romantic dinner. When this does not happen, she angrily kicks David out of their home.
Two globetrotting private eyes with diferente styles team up, guarding their true identities at all costs from the bad guys‒and from each other.
