Your boss works illegally and his business is all about monkey business. His business is smuggled goods, so you can expect that it would be hot for the police. You can't do anything about that as you are just a mere driver. Your job is to pick-up the smuggled goods and loads it to the dock for shipping.
The idea here is to pick all the package in the airport and put it on the loading station. There will be many police cars trying to stop you and will bump you till your car crashed. You should avoid collision with these cars as that will damage your car.
