Fifty-year-old Sharon Temple Sowerby grew up caught in a tug of love between two mothers. When she was a girl, Sharon discovered that the mother she knew of as 'mam' was not in fact her birth mother. Over the years, as the truth gradually emerged, Sharon discovered that she had been taken from her birth mother at only one hour old and given to a couple desperate for a child, who brought her up as their own. But Sharon also discovered that legally she was never theirs. Sharon's birth mother had refused to ever sign adoption papers and on several occasions actually asked for Sharon back. This tug of love continued until Sharon moved away to Germany with her parents. Heartbroken by these discoveries, Sharon has been searching for her birth mother for nearly thirty years but without success. Watch what happens when we take on this seemingly impossible search and meet the man searching for the same woman, who is also his birth mother.
