Vivacious Alice Lacey couldn't be more different from her sister in law, the bitter, ambitious Cora. Alice is married to John, Cora to his hapless younger brother, Billie. Both women give birth to sons on one chaotic night in 1940. It is Cora's jealousy and resentment that prompts her to swap her puny baby for Alice's beautiful son. With Alice's marriage in tatters, because the disfigured John rejects her unable to believe that she still loves him when he looks like 'a monster', she borrows money from Cora in order to purchase the lease of the tiny hairdresser where she works. Alice is talented; the business thrives and a chain of salons becomes Laceys of Liverpool. The relationships between the cousins, Cormac and Maurice, their parents, Alice's three girls and their eventual husbands and children combine to give a unique picture of Liverpool in the last sixty years of the twentieth century.
