Eagle Street is a little backstreet off the Tower Bridge Road market, home to a close-knit community of diverse characters. Dora and John Weston live in one of the small terraced houses with their five children. Amongst their neighbours are the two street gossips, Doris and Phyllis, who know everyone's business; Dick Conners, the local drunk, who needs a good woman to save him from himself; and aged Bill Simpson, who tends his pigeons and watches the glorious sunsets from the flat roof of Sunlight Buildings.
It was on this same roof in the summer of 1940 that Linda Weston first fell in love with Charlie Bradley - a childhood crush which has stood the test of separation during the war. Now Charlie has returned to Eagle Street, keen to make his own way in life, and a good future for Linda. When both Charlie and Linda are offered jobs by the notorious Carter brothers they jump at the chance. But the rival "Kerrigan" gang hears of the Carters' success in the French perfume business and decides that something needs to be done about it. And when harmless rivalry becomes open war, the lives of unsuspecting Charlie and Linda are really put at risk . . .
