London, April 1943. A little over a year since she married Captain Charles Mayhew and he went away to war, Emmy Lake is now in charge of "Yours Cheerfully," the hugely popular advice column in Woman's Friend magazine. Cheered on by her best friend Bunty, Emmy is dedicated to helping readers face the increasing challenges brought about by over three years of war. The postbags are full and Woman's Friend is thriving. But Emmy’s world is turned upside down when glamorous socialite, the Honorable Mrs. Cressida Porter, becomes the new publisher of the magazine, and wants to change everything the readers love. Aided by Mrs. Pye, a Paris-obsessed fashion editor with delusions of grandeur, and Small Winston, the grumpiest dog in London, Mrs. Porter fills the pages with expensive clothes and frivolous articles about her friends. Worst of all, she announces that she is cutting the "Yours Cheerfully" column and her vision for the publication's future seems dire. With the stakes higher than ever, Emmy and her friends must find a way to save the magazine that they love.
