In Return With Glory, Dalton Trumbo is one of the most famous writers of Hollywood in the forties. He writes scripts for very successful films and that makes him a lot of money. Enjoy a well-deserved fame, but all that is going to come down right away.
In those years is inaugurated the well-known like witch hunt in Hollywood, with the creation of a commission that persecutes to all those that are suspected of sympathizing with the communists.
Dalton is one of them, so it ends up on the blacklist, which makes it from success to not having a job. Overnight he is left with nothing, because no one calls him to make movies.
That forces him to think and finally finds the solution. From then on, his scripts will not bear his name, but will sign them with a pseudonym that will hide his identity from the Committee on Un-American Activities.
