Over a drug-fuelled weekend in Dublin, Jason reconnects with his estranged brother, a recovering addict living on the streets.

Claudia, a lonely single mother and school nurse, is longing for connection. Her opportunity to be a hero comes when a young child in her community – Emily Winter – goes missing. Claudia becomes embroiled in the case and fixated on uncovering the truth. However, her fascination quickly begins to turn to obsession, not only with what happened to Emily, but also with the Winter family at the heart of the case - Emily's grief-stricken father, Owen; her cold mother, Sabine, and her twelve-year-old brother.
