A spoiler is a piece of information in an article about a narrative work (such as a book, feature film, television show or video game) that reveals plot events or twists.

Spoilers are often preceded by a spoiler warning. On Wikipedia, it is acceptable to cite reliable sources that use spoiler warnings.

It is not acceptable to delete information from an article about a work of fiction because you think it spoils the plot. Such concerns must not interfere with neutral point of view, encyclopedic tone, completeness, or any other element of article quality (for example, WP:LEAD).
