Cover-up in the context of "Thriller film"

Thriller is a genre of fiction with numerous, often overlapping, subgenres, including crime, horror, and detective fiction. Thrillers are characterized and defined by the moods they elicit, giving their audiences heightened feelings of suspense, excitement, surprise, anticipation and anxiety. This genre is well suited to film and television.

A thriller generally keeps its audience on the "edge of their seats" as the plot builds towards a climax. The cover-up of important information is a common element. Literary devices such as red herrings, plot twists, unreliable narrators, and cliffhangers are used extensively. A thriller is often a villain-driven plot, whereby they present obstacles that the protagonist or hero must overcome.

Tampering with evidence, or evidence tampering, is an act in which a person alters, conceals, falsifies, or destroys evidence with the intent to interfere with an investigation (usually) by a law-enforcement, governmental, or regulatory authority. It is a criminal offense in many jurisdictions.

Tampering with evidence is closely related to the legal issue of spoliation of evidence, which is usually the civil law or due process version of the same concept (but may itself be a crime). Tampering with evidence is also closely related to obstruction of justice and perverting the course of justice, and these two kinds of crimes are often charged together. The goal of tampering with evidence is usually to cover up a crime or with intent to injure the accused person.
