A tragi-comedy of sectarian bigotry in Glasgow. Set in Glasgow on the day of the Orange Walk, Bill MacWilliam is determined that his son, Cameron, will join him on the walk. However, prompted by his mother's recent death, Cameron has started to question his father's beliefs. Throw in the arrival of the staunch Irish Catholic spinster from downstairs and her pregnant niece. Comic chaos and dramatic conflict is the result. Father is pitted against son and niece against aunt as old prejudices are questioned and new ideals sought.
