wEeK 29- SuBmArInE aDvEnTuRe

So there we all are the English 3 honors class. In a submarine that is immune to all destruction... WWIII happening in the world above us we're all perfectly safe. We have suits just in case the sub breaks that make us immune to all nukes and radiation. So were casually driving right? And out of nowhere we run into a stupid city under the water that made our sub break down. We all went out to help fix it, and I found some sign that said "Welcome to Atlantis" Thinking this was stupid we fixed the sub and drove off away from the stupid city that delayed our under water trip.. the end?
