What if you could remember every last detail of your life?

Eve knows what her colleagues had for lunch last April. She remembers everyone who passes through the care home she works at long after they've gone. Like her museum of tiny treasures, her life is small and manageable.

And what if you couldn't even remember your name?

'Adam' is found wandering down the central reservation of the M25. He has no memory of how he came to be there.

As Eve works with Adam to help him discover who he once was, her world begins to open up. But when Adam remembers his past, can Eve possibly be part of his future?
