After a few "mild" attempts on each other's lives, fueled by a mutual sense of betrayal, the marital spat culminates in a high-octane fight in the Smith house. After a long, evenly-matched fight, with their house shot to shambles, they wind up with guns in each other's faces. John balks, and lays his gun down; Jane finds she cannot shoot her spouse either, and both succumb to their love instead. Mr. and Mrs. Smith reunite and rediscover each other.
