A family's race against time to find the baby they believe DNA testing proves was switched at birth.

It’s the perfect gift for the person who already has everything. It promises to tell you who you really are, and how you’re connected to the world. A present that will reveal your genetic past – but could also disrupt your future.

In the second series of The Gift, Jenny Kleeman looked deeper into the unintended consequences - the aftershocks - set in motion when people take at-home DNA tests like Ancestry and 23andMe.

This included "Switched"; the stories of two women who discovered they had been accidentally swapped at birth in a West Midlands hospital in 1967– all due to an Ancestry DNA test, received as a Christmas gift.

As soon as the episode aired, people began to contact Jenny with tales of other incidences of accidental baby swaps - and one in particular stood out.
