"Plunge in" means to start doing something with great enthusiasm and energy, without any hesitation or fear. You can use this expression when you're about to start a new project or activity and want to emphasize your determination to fully engage in it. For example, you might say "I'm just going to plunge in and start writing my essay" or "Let's plunge in and see how far we can get with this puzzle." It can also be used in situations where you need to take a risk or make a big decision without fully knowing the consequences, such as "I decided to take the job offer and just plunge in, even though it's a bit risky."
