Excavation and Interpretation: A Brief Review of the Principle of Prohibition of Double Jeopardy in the Film "Double Conspiracy"

: The paper is based on the story background of the movie "Double Jeopardy" and digs into the principle of prohibiting double jeopardy during the implication. In the film, Margaret, who is Libby's cellmate after her imprisonment and also a good lawyer, has reminded Libby that if Nick is still alive, she can return the favor to Nick unhindered, because a person cannot be prosecuted twice for the same crime. This prompted the article to ponder the doctrine of double jeopardy from three perspectives: film, jurisprudence, and reason. The article argues that the principle of prohibition of double jeopardy has its research value and application significance both at the theoretical level and at the practical level.
