Alice Baker knew she had special gift, but it was only after she qualifies as a nurse, working in Casualty in a busy London hospital, she realises she could draw pain from her patients. She always has a severe reaction until Dr John Warford, also with special gifts and a 'time traveller' shows her how to control them. He explains if she does not, she could be regressed to a different time. On a day her mentor is off duty, Alice saves her brother after a near fatal motorbike accident. It sends her into a coma, and she wakes in war torn London in 1940. Befriended by a pretty cockney, Lizzie Brown and joined by time traveller John Warford, she stays at the Nag's Head Pub in Holloway, run by Lizzie's father Fred and step mother, Phyllis, who is not all she seems. Alice discovers there are people, also time travellers, with malicious intent trying to disrupt the outcome of WW2, of which Phyllis is a powerful member. Alice overhears Phyllis and another discussing their plans, but does not hear the whole of it. She is banished from the Nag's Head and becomes a Red Cross nurse, where she discovers Phyllis' group have access to a small amount of the 'Spanish Flu virus' of 1918. She hears this is being held in a laboratory at Porton Down near Salisbury. Alice becomes a nurse at the Harvard Hospital in Salisbury, where there are recovering Air force pilots. Phyllis plans to infect some of the pilots, which would have stopped the 'Battle of Britain,' and so possibly lost the war. In a dramatic confrontation, Alice and John Warford(who have become romantically involved) and other helpers manage to vanquish Phyllis and her followers, with surprising results.
