'Who am I? Why am I here? Why did my mother give me away?'

On the surface, Luke and his girlfriend Hannah seem to have a perfect life. He's an A&R man, she's an arts correspondent and they are devoted to their new-born son Samuel.

But beneath the gloss Luke has always felt like an outsider. So when he finds his birth mother Alice, the instant connection with her is a little like falling in love.

When Hannah goes back to work, Luke asks Alice to look after their son. But Alice - fuelled with grief from when her baby was taken from her 27 years ago - starts to fall in love with Samuel. And Luke won't settle for his mother pushing him aside once again...
