If a jury is hung, the judge may declare a mistrial, which means the trial starts all over again from scratch. It's like hitting the reset button - all the evidence has to be presented again, and a new jury has to be selected. This can be frustrating for everyone involved, especially the victims or the defendants who are waiting for a resolution.
In some cases, the prosecution and defense may decide to negotiate a plea deal instead of going through another trial. This is like finding a compromise on the movie night - instead of watching a rom-com or an action film, you decide to watch a comedy instead. Both sides may not get exactly what they want, but they can find a middle ground that works for everyone.
