Eilidh, bright, headstrong and feisty, gets sparkling exam results that confirm her university place. Her boyfriend reveals he has deceived her. In the ensuing argument she is knocked unconscious. She arrives in 1984, in an Ethiopian refugee camp, where she nurses a dying child, then a wounded aid worker before wakening back home in present-day Scotland. She encounters Walter, who is in the early stages of dementia. Over a 48-hour period Eilidh finds herself transported to various locations in Europe and North America, and time periods from the previous fifty years. Each time Eilidh 'travels' she meets younger versions of Walter, ultimately falling in love with and marrying him. Eventually Eilidh travels to WW2 blitzed Liverpool and meets her grandmother's sister, a fellow time traveller. She learns that she has to decide whether to give up her life in 2019 irrevocably and time travel one final time to commit to a life with Walter.
