Set in 1906 London, the narrative finds Doyle grappling with personal turmoil — including his dying wife’s wish for him to marry another woman — while becoming embroiled in the case of George Edalji, a wrongfully convicted man of Indian descent. The film also delves into the plight of Oscar Slater, another victim of judicial injustice, as Doyle applies his investigative prowess to real-world cases that mirror his fictional detective’s adventures.
