• Before making a single edit, Tropedia EXPECTS our site policy and manual of style to be followed. Failure to do so may result in deletion of contributions and blocks of users who refuse to learn to do so. Our policies can be reviewed here.
  • All images MUST now have proper attribution, those who neglect to assign at least the "fair use" licensing to an image may have it deleted. All new pages should use the preloadable templates feature on the edit page to add the appropriate basic page markup. Pages that don't do this will be subject to deletion, with or without explanation.
  • All new trope pages will be made with the "Trope Workshop" found on the "Troper Tools" menu and worked on until they have at least three examples. The Trope workshop specific templates can then be removed and it will be regarded as a regular trope page after being moved to the Main namespace. THIS SHOULD BE WORKING NOW, REPORT ANY ISSUES TO Janna2000, SelfCloak or RRabbit42. DON'T MAKE PAGES MANUALLY UNLESS A TEMPLATE IS BROKEN, AND REPORT IT THAT IS THE CASE. PAGES WILL BE DELETED OTHERWISE IF THEY ARE MISSING BASIC MARKUP.

A standard television plot. An assignment is received in The Teaser. A planning session is held (Avengers Assemble). Then comes The Caper or The Con, using a Master of Disguise and an A-Team Montage. The resolution is as close to end of The Tag as possible.

At about the 40-minute mark, there is a Pseudo Crisis.

The trope takes its name from the series Mission Impossible, whose Impossible Mission Force did one of these every week. As such, note that not every impossible mission is an Trope Workshop:Impossible Mission.

For missions that actually are impossible, see Impossible Task.

Not to be confused with the video game Impossible Mission. Also see Suicide Mission.

Examples of Impossible Mission include:
  • Despite its few episodes, Firefly did two of these, in "Ariel" and in "Trash".
  • Mercilessly parodied in the Whose Line Is It Anyway? game "Improbable Mission," which had agents given missions involving high stakes but ordinary tasks, such as doing laundry or mowing the lawn.
  • The eponymous task of "Inception" in the film of the same name.
