Cat Hogan returns to West Meath upon her mother's sudden death--she had an accident at home and died (or was it an accident?). Blood is about old secrets, older betrayals, mind games, and the lies family tell each other.

Cat Hogan is an isolated woman on the run from her past, a past she is forced to confront when the sudden 'accidental' death of her mother Mary draws her back to the family she has spent the last decade trying to avoid. Although her death is seemingly 'accidental', Cat isn't convinced and suspects her father Jim (Adrian Dunbar) might have been involved in her untimely demise.
