One day he dies, and no one can stop them roaming across his house and lands. However, when one of Mr McGregor’s relatives inherits the house, he finds much more than he bargained for. What follows is a battle of wills between the new Mr McGregor and the rabbits. When he starts to fall in love with Bea (Rose Byrne), a lover of nature, his feelings towards them begin to change. But is it too late?
