In the seaside town of Kinlough, on Ireland's west coast, three old friends are thrown together for the first time in years. They - Helen, Joe, and Mush - were part of an original group of six inseparable teenagers in the summer of 2003, with motherless, reckless Kala Lanann as their groups white hot centre. Soon after that summer's peak, Kala disappeared without a trace.
What happened to her ?
