When the bodies of wealthy matriarch Ursula Kennedy and her farmer husband Jimmy are pulled from the slurry pit, shock ricochets throughout the family and community. Everyone has questions, including the gardai.

Was this a tragic accident? Or is there more to it than meets the eye? Their son Rob, once destined for a high-flying legal career, is now involved in the family business.

Meanwhile, Christina, the victims' fragile daughter, is carrying a private pain she's never been able to speak about. As vivid memories rush back of another tragic death on the farm some sixteen years ago, a toxic secret is set to come to the surface, one that has been simmering for decades .
