The Brightwells live in Moss Street in a shabby area of London's Shepherd's Bush. Maggie Brightwell's father was killed in the Blitz by a bomb that also injured her brother Tom. Yet Maggie is a lively, warm-hearted girl. She works as a typist in central London and becomes good friends with Chloe Anderson, the spoilt daughter of her rich boss. When her boss begins to take a more than paternal interest in Maggie, she is horrified and quickly changes jobs, becoming an assistant in a run-down flower shop in Moss Street. She soon falls for the happy-go-lucky owner Jack Radford and they marry. But their happiness is threatened by a developing relationship between Maggie and her best friend Chloe's new charismatic husband. Maggie is determined not to hurt those closest to her and provide a better life for her family, but can she resist temptation?
