Officers from the RSPCA investigate reports of animal cruelty and neglect on a farm, only to discover a 5-year-old boy curled up asleep in a dog bed, amidst filth and squalor.

He has severe physical and cognitive impairments, and no one outside the family seems to know of the existence of little Jacob.

When he arrives in the Allen household, a terrified Louise wonders how on earth she will cope looking after a child with his level of physical and emotional damage. With the support of veteran social worker, Mary, the fight begins to get Jacob the support he needs – as medical investigations begin to reveal more shocking details about Jacob’s story.
