Plot
In 1881, 18 months after his father's death, Louis Wain, the only male and eldest of the Wain family, becomes the primary breadwinner. He supports five sisters and his mother working part-time as an illustrator for The Illustrated London News under editor Sir William Ingram. Ingram offers him a full-time job, but Wain declines in order to try his hand at composing music and playwriting; which he hopes will support the family but neither venture is successful.
Louis hires Emily Richardson to be the new governess for his sisters. The two become instantly attracted to each other, much to the dismay of the eldest sister, Caroline. Louis decides to take the full time position in order to keep Emily as the governess. One night, Louis takes the family, and Emily to the theatre to see The Tempest as an educational trip. She comforts Louis in the men's restroom after he has a recurring nightmare about drowning during the performance, but inadvertently causes a scandal when nosy neighbor Mrs. DuFrane tells people about the incident. Embarrassed, Caroline fires her that night. Before she can leave, Louis professes his love for her and they begin a courtship.
In 1884, the couple marry, which causes another scandal for the Wain family due to her being 10 years older than him; and her social status as a governess which is considered lower class. They move into a house in Hampstead, where Louis takes additional work as a freelance artist to continue supporting his mother and sisters. Months later, Emily is diagnosed with breast cancer. While walking in the countryside, they take in a stray kitten they name Peter, to relieve the grief of Emily's cancer. The practice of keeping a cat as a pet was unusual in the Victorian era. Louis begins painting realistic pictures of Peter, but the paintings become more unusual as Emily's condition worsens. He makes the cats more anthropomorphic, with them engaging in human behaviour.
A financial crisis in England causes the paper to cut staff. Sir William tells Louis that he will have cut his workload, and advises him to use the extra time to spend with Emily. After showing Emily his work, she encourages him to show them to Sir William who uses the drawings in two pages of the Christmas edition. Although the edition becomes a success, Emily dies months later. Louis begins drawing more cat pictures to cope with losing the love of his life, creating whole cat societies, but it also begins to show Wain's detachment from reality.
By 1891, Wain's cat pictures become enormously popular. They are featured on postcards, greeting cards, and other print materials. Wain also sends some of his drawings abroad. The drawings change peoples' perception of cats, making them acceptable as house pets. He hosts cat-themed events and is made chairman of The National Cat Society. Despite the popularity of his work, the family remains in debt. Wain fails to copyright his work, so he cannot profit from any reproductions of the art. To make matters worse, Marie, the youngest, begins to show signs of mental illness. The debt causes the family to be evicted from the Hampstead home.
Sir William allows the family to stay at one of his properties at a reduced rate. Marie is admitted to an asylum, and Peter dies, causing Wain's own mental health to deteriorate. In 1907, Wain travels to New York, on a trip sponsored by newspaper magnate William Randolph Hearst. Wain hopes to forge a successful career in America to alleviate his debts. He meets Max Kase, who tells him that people love the pictures. Days after arriving, he receives news that his mother has died of influenza. He has some success in NYC, but returns to England in 1914 at Caroline's request.
Upon arriving home, Louis is given the news that Marie, too, has died from influenza. Sir William also dies, succumbing to his gout. The family is evicted, and moves into a smaller flat in London. Louis continues to work as Britain enters World War I. He hits his head trying to jump off a double decker bus and falls into coma, where he sees a vision of 1999. Coming out of the coma, he is inspired to design futuristic-themed cat toys. The toys are manufactured, which looks to change the Wains' fortunes, but their hopes are dashed when a German U-boat sinks the ship carrying the toys.
In 1917, Caroline dies. The losses of Emily, his mother, Marie, Peter, Sir William and Caroline causes Louis to go on a series of violent mental breakdowns. In 1924, his sisters are forced to have him committed to the Springfield Mental Hospital in Tooting. Dan Rider, an official inspecting the mental institution, recognizes Louis; in 1881 Louis drew his dog Cleopatra for free while they rode a train. After speaking with Louis, he starts a campaign, along with Wain's three remaining sisters (who never married), to raise money that will place Louis in a better facility that allows cats and provides patients access to outdoors.
The campaign gets an enormous response, as thousands of admirers of Wain's art contribute. The author H.G. Wells, also a fan of Louis's work, along with other prominent British figures, assist with the effort. After raising the money needed. Louis is transferred to Bethlem Royal Hospital in Southwark, where he has a cat companion. In 1930, he is admitted to Napsbury Hospital in St. Albans.
Guided by Emily's spirit, and with his journal and a cut-out piece of Emily's old scarf, Louis goes out to the painted countryside, where Emily once told him that he would find her.
