When 3-month-old Max is abducted, his parents are plunged into their worst nightmare. Devastated mum Sarah only took her eyes off him for a second, but that doesn't stop her guilt. Even husband Jake can't hide his anger that their little boy went missing on her watch.

By contrast there are smiles and celebration at a caravan park in Lincolnshire, as baby Blaze is introduced to the Star family. Jenna and Gary are delighted with the new addition to their family. He is their fourth child and a real object of delight to their eldest - fifteen-year-old Willow - who once again will raise the child.

But trouble is brewing for the Star family. Willow is concerned by the desperate online appeals from Sarah and Jake, baby Max has neonatal diabetes and without regular treatment will die. As baby "Blaze" becomes seriously ill, Willow makes a shocking discovery. What is the truth about her family? And how far will they go to hide their deadly secret?
