Impossible but true, because Henry suffers from a rare condition where his genetic clock periodically resets and he finds himself pulled suddenly into his past or future. In the face of this force they can neither prevent nor control, Henry and Clare's struggle to lead normal lives is both intensely moving and entirely unforgettable.
