First networking event tonight and I have no idea what I’m doing

Please help! I’m going to a networking event tonight and I don’t know anyone. I’m not sure what I’m supposed to say or do or how to act.

The lady said it’s business casual so I’m not in a suit or anything. It’s a company sponsored event so we all work for the same company, but being at the bottom of the food chain is definitely intimidating. I feel like this is a great opportunity to give my career a good nudge. Any advice?
