This is one documentary that should get the country talking. Financial journalist Ian Kehoe meets the overseas investors who have acquired significant chunks of the Irish property and business sectors - including a representative of the US real-estate firm that has become the largest commercial landlord in Dublin, and a London-based magnate who is keen to add to his portfolio of bars and pubs. The presenter considers the extent to which investors can make a positive difference to the country, and asks whether some may be taking advantage of the economic calamity.
