||There's nothing special about the O'Maras. They're about as ordinary as you can get. Just a regular Irish family living in a south Dublin suburb, muddling through life pretty much like the rest of us. However, Sarah's eldest daughter Rosie has become restless and unpredictable as of late. Despite husband Eamonn's reassurance, Sarah is concerned?with good reason. She sowed a few wild oats of her own in her youth and doesn't want her increasingly wayward daughter following suit. She knows what trouble it can get you into. Then, out of the blue, Rosie's natural father shows up. Of course Sarah and Eamonn always knew this could happen but prayed it never would. This is the Worst Case Scenario, especially for the impressionable Rosie. For he is the glamorous cosmetic surgeon to celebrities: Dr MJ Murphy, from a wealthy Argentinian family in Buenos Aires.
