Basically the ending was hits were put on both John and Jane. The people after them came to their house and a whole lot of shooting and diving etc went on, ended up thehouse being burnt down due to a bomb thrown in the basement area which John kicked away, but it landed near fuel. John and Jane used the confusion caused by the smoke to drive away. Not sure why, but they ended up in a homeware store, where they teamed up to 'kill all the bad guys'! Not just by shooting, but using various implements (e.g. knives being sold by the store). They ended up killing all the people after them and at the end, John and Jane are talking to the marriage counsellor, saying how great their marriage was and how well it was going.
