Every word in the Oxford dictionary should not only cover the scope, meaning and pattern, but also correct the spelling mistakes left over from history, correct pronunciation, ensure the accuracy of language use, and record the minor differences of each word in detail according to the category. In addition, they must record every step of the evolution of meaning over hundreds of years. Just then, a package from far away solved the problem for them. The package came from a mental hospital in Berkshire. The volunteer who delivered the package was William Chester Miner, also known as Dr. Miner.

Miner provided the origin and evolution of more than 1000 words in the package. In addition to providing a lot of available information, he also invented a classification tool in a hurry, which helped Murray greatly improve his work efficiency. With the help of Miner, Murray's work is progressing rapidly, and soon the first volume of the Oxford English Dictionary, which collects all English words from "A" to "Ant", will be published successfully. Miner is not a real doctor, but a psychopath, madman and murderer imprisoned here.

When he saw Murray's open letter Dictionary, he devoted himself to reading and learning, praying for self-salvation in the book. "Standing on the spine of the book, I can jump over the fence in front of me, and with the wings of words, I can reach the top of the world. This is freedom. Only by studying can I have no pursuers in my life. "

He and Murray, two people who have never met before and have no intersection, came together because of the compilation of the Oxford English Dictionary, and started a great course of cooperation. I thought with Miner's help, the compilation work would get better and better. Unexpectedly, his life experience has become an obstacle again: people don't want American murderers to defile the Oxford Dictionary.

Miner won the freedom of repatriation and the right to continue to write his own dictionary. The trust and agreement between the two souls finally set off a big project of dictionary compilation. And this is also the most controversial part of this film.
