Max drives a taxi at night for a living. At the end of each shift he stops for a cup of tea in the park and has a chat with his wife’s ghost. It is a warm loving (normal) relationship. After a series of violent events in his neighbourhood and the police marking the investigation into her murder as open but inactive Max decides he needs to get justice for himself and others.
As his violence escalates the Police begin to focus on him. This culminates in Max deciding to end it in a death by cop scenario so he can be with his wife and hopefully draw some attention to the problems in the neighbourhood.
