A log line or logline is a brief (usually one-sentence) summary of a television program, film, short film or book, that states the central conflict of the story, often providing both a synopsis of the story's plot, and an emotional "hook" to stimulate interest.[1] A one-sentence program summary in TV Guide is a log line. "A log line is a single sentence describing your entire story,"[2] however, "it is not a straight summary of the project. It goes to the heart of what a project is about in one or two sentences, defining the theme of the project...and suggest[ing] a bigger meaning."[3] "A logline is a one-sentence summary of the story's main conflict. It is not a statement of theme but rather a premise."[4]
"A logline...helps content creators simply and easily sell their work in a single sentence, because the emphasis is on what makes their property unique...the logline provides the content creator with a concise way to focus on the three main anchors of their writing," the protagonist, the protagonist's wants (goal(s) or desire(s)), and what is at stake (risks).[5]
Narrative elements often referenced in a logline include the setting, protagonist, antagonist, inciting incident, and a conflict and a goal (the conflict's resolution).[6] Change, such as character growth, and action should be suggested.[3] A log line should contain four facts: "the main character, what the main character wants," the villain(s) or obstacle(s), "standing in the way," and, "the unique aspect(s) of the story."[7]
