Harvey Shine és un músic de Nova York que treballa en el món de la publicitat. Harvey passa per un mal moment tant a la seva vida professional com personal, però durant un viatge a Londres coneix Kate, una dona soltera de mitjana edat amb una vida molt grisa. Malgrat això, Harvey s'hi sent atret, i entre ells s'establirà una relació que canviarà per sempre les seves vides.
Mr. Selfridge recounts the real life story of the flamboyant and visionary American founder of Selfridge's, London's lavish department store. Set in 1909 London, when women were reveling in a new sense of freedom and modernity, it follows Harry Gordon Selfridge ('Mile a Minute Harry'), a man with a mission to make shopping as thrilling as sex. Pioneering and reckless, with an almost manic energy, Harry created a theater of retail where any topic or trend that was new, exciting, entertaining - or just eccentric - was showcased.
