A tragic secret, a broken family, a lost boy - who was Edward, and what happened to him? Life for Jen and her family, including 11 year old, autistic son Ned, hasn't always been easy, but things are improving. Ned is thriving in the right school, and getting the support he needs to navigate his way through an alien and sometimes frightening world. But Jen is troubled by something from her past. She's haunted by a nightmare that has disturbed her since childhood, and she's increasingly uneasy about her relationship with her cold, distant parents - what are they hiding from her? 'Our Lost Boy' follows Jen's search for the truth, taking her back to her childhood home in Yorkshire where shocking memories are reawakened. Jen and her mother, Maureen, have been pulled apart by a tragic secret, but when the truth is out can they mend their broken relationship? Can Jen forgive Maureen, and can Maureen forgive herself? And what about Ned - can the 21st century offer him, and others like him, the future that Edward was denied?
