Martin and Ann meet their new neighbour Paul. Ann believes that he will be a welcome addition to the Close, but Martin is not so sure.

Martin's dislike for Paul intensifies when Paul manages to get Martin relieved of all his duties on the Resident's Committee. Ann mistakenly believes she may now have some quality time upcoming with Martin.

It's time for members of the Close to go on a holiday outing, and some wish to repeat an earlier trip to the Bavarian Alps. But Paul has something altogether different in mind. Will Ann and the rest like it?

Martin organizes a fund-raising dance. Paul innocently lends a helping hand, and in doing so mercilessly interferes with Martin's arrangements. How will Martin retaliate?
