With a failed marriage behind her, La -- short for Lavender -- moves to the Suffolk countryside on the eve of the Second World War to nurse her broken heart. Lonely and at a loss, a friend encourages her to bring the villagers and the men from the local airbase together by forming an amateur orchestra. One of her musician recruits is Feliks, a handsome and enigmatic Polish refugee. A friendship begins to blossom between the two, and La finds her feelings stirring to life again.

Poignant, tender and inspiring, La's Orchestra Saves the World celebrates the power of love and friendship in the shadow of the collective tragedy of war, as well as the extraordinary healing power of music.
