Okay kiddo, have you ever played a game with your friends and decided to bet on who will win? It could be a race or a board game, and you might bet a toy or a piece of candy. Well, some grown-ups also like to bet on things, especially on the outcomes of sports games like football or basketball.
These grown-ups are called bookies. They don't just bet for fun though, they also make money by taking bets from other people and giving them a chance to win more money if their prediction is correct. It's like they're running a store where people can make bets.
Now, there are laws in some places that only allow certain people or businesses to be bookies, and those laws can be complicated. The movie "Bookies" is about some college students who become bookies themselves and start taking bets from their classmates. But they soon get in trouble with the law and with other bookies.
So, the movie is really about the dangers of breaking the law, especially when it comes to gambling. Gambling can be fun, but it's important to do it legally and responsibly.
