Debbie Murphy is driving to work in the city of Liverpool, when she is involved in a serious car crash. She suffers major injuries including some brain damage.
She is transferred to Addenbrokes Hospital in Cambridge as she is in need of specialist care for her brain injuries. She remains in a deep coma for a year. When she wakes up she is astonished to find that she is back in the year of 1980.
Her grasp of reality is confusing with so many conflicting messages of when and where she is. She soon realises that 1980 has significant memories for her.
The main memory which is going round and round her head, is the assassination of
John Lennon who gets killed by Mark Chapman on the 8th December 1980.
She believes that she has been sent back in time to save him.
No matter what it takes or costs her determination alone has convinced her that she must do it, why else is she in this time zone if not for that reason?
