When Maureen Galyon gave birth in 1951, she had no idea she was expecting two babies – let alone conjoined twins. The tots, joined at the torso, were not expected to survive the night as baffled doctors tried to work out if they could be separated.

And, as their health declines and they near their dying days, the pair have opened their doors to a documentary team to reveal the secrets of their extraordinary life together. Although every day is a struggle as the men have to coordinate the simplest of tasks, they have a close, loving relationship and are able to live together in their own home in Dayton, Ohio.
