The plan is simple. It's an average night and the hero is settling in for a quiet, peaceful night. Maybe they want to go to a party, maybe they need to pick up their friend. Maybe they just want to make through the night.
Of course, it's not that simple. It never is. The powers that be keep putting roadblocks in their way. On their way to the mall, their car breaks down. The man they flag down for help steals the car. The first officer on the scene is a paranoid lunatic. The problems keep piling up and what started out as an ordinary day turns into...well, One Crazy Night.
Stories like this take a conflict that could be stretched out over several days and compress it into only a few hours.
One common element is this kind of plot is that the protagonists have to complete their mission and get back their home/headquarters/etc. (and possibly clean things up) before their parents/bosses/etc. get home/back and find out what's been going on.
Another is the nature of the event. They have to be extraordinary. For example, Who's Afraid of Virginia Woolf? takes place over one night, but the events of the story are fairly mundane. It's not this trope, it's Extremely Short Timespan.
Note: This trope is nearly always a comedy trope; it lends itself well to comedy. However, there are serious examples, such as A Christmas Carol.
If the events of the plot take place over more than 24 hours, it isn't this trope. Subtrope of both Extremely Short Timespan and A Simple Plan. The Wild Teen Party will often overlap with this. Compare and contrast with What Did I Do Last Night?, where the character pieces together a similar adventure the morning after. Compare It Was a Dark and Stormy Night.
