Charles Darnay is on trial for being related to an executed noble, (keeping in mind that during the French Revolution, people were killed by just talking good about nobles.) The Jury and the Judge are not on his side.
Darnay is found guilty, and is taken to prison. He is to be killed by the Guillotine the next day.
Back at the house, Darnay's wife, two kids, and father in law are weeping, awaiting the execution of Charles. Sydney Carton, an English Lawyer obsessed with drink, and loves Darnay's wife, walks in and Darnay's daughter Luice, gets on her knees and begs her "Uncle Sydney" To save her father. (Louice and Sydney Carton were close, and Louice called him Uncle even though they have no relation)
Carton promises Luice, and goes into the street to form a plan. He stops at a wine shop to grab a drink, where the owner is a man named Monsieur Defarge is talking to his wife. The Defarge's talk about how they turned in Darnay to the police, and how they plan to kill the rest of Darnay's family. Suddenly a plan comes to mind.
Sydney tells his plan to Jarvis Lorry, an English banker and fiend to Charles Darnay who came to Paris for Darnay's trial. Lorry is confused, he does not understand the plan and also does not understand why Carton wants to save Darnay, since they came to blows once over Darnay's Wife. Sydney simply tells him to get the Darnay Family out of Paris.
Sydney Carton goes to Darnay's prison cell, and tells him to change clothes with him. Darnay is confused, but obeys. And then, after apologizing, Carton drugs him so quickly, so he could not resist. Darnay is out cold. Because they switched clothes, the guard takes Darnay outside. Lorry managed to get the Darnay family out of Paris on time, Carton was executed in Darnay's place, Everyone else escapes to England. The End
