Highway Harry, the city centre's Maintenance Team leader moves into a quiet cul-de-sac near to Southampton docks but his new home is plagued with mishaps, a water leak, a broken boiler, birds caught in the chimney and a leaking roof. When Harry attempts to install a new bathroom, a blocked pipe bursts flooding his own and his neighbours gardens.

Bennie Barrier and his team meanwhile are helping out at the cruise terminal where Lady Courtney Cruise is in port reloading with passengers and the Maintenance Team are fitting her with a new luggage ramp. When Bennie Barrier receives the call from Harry, his team head to Harry's new house to help him and the water company fix the mess that he has created. Whilst they are there, Bennie Barrier discovers tension amongst the neighbours, is Harry's string of disasters just bad luck or someone else trying to sabotage Harry's fresh start?
