The true story of eccentric British artist Louis Wain (Benedict Cumberbatch), whose playful, psychedelic pictures transformed the public's perception of cats forever. Set in the early 1900s, we follow Wain as he seeks to unlock the "electrical" mysteries of the world and, in so doing, to better understand his own life and the profound love he shared with his wife Emily Richardson (Claire Foy).
