Siva Sithambram (Raja Ganesan), your average next door neighbor’s mundane life takes a hilarious turn when a distant relative Pat (King Ratnam) and his family from London decide to stay with him for the duration of their trip to attend a family wedding. Riddled with financial problems, an aging, unmarried daughter and a nagging wife, expectations run sky high in anticipation of the timely arrival of his diasporan guests. But little does he know, that all is not what it seems with the Pat family.
