Okay, so imagine you're watching a movie. This movie is called "One Night" and it is about two people named Bea and Danny. They meet each other at a club and decide to spend the night together.
But, the interesting thing is that the movie doesn't just show them together for the whole night. Instead, it shows what happens to each of them separately throughout the night.
So, for example, it shows Bea going to a party with her friends and getting into a fight with one of them. It also shows Danny trying to buy drugs and getting into trouble with the people who sell them.
Throughout the night, the movie switches back and forth between Bea and Danny's separate experiences. But, you can tell that they are still thinking about each other and wondering if they will see each other again.
In the end, they do see each other again, but it's a bit of a surprise how it happens. To find out what happens, you have to watch the movie for yourself!
