Arbitrary Rescue

You have just broken up with the love of your life and are feeling miserable so you end up doing something impulsive, a late night swim in the ocean on your own. Distracted and distraught you don’t notice the tide pulling you into deep water until it’s too late. You try to swim back to land but it recedes until you can’t see it in the dark anymore. You drift on in the night for hours until your foot bumps against something hard in the black depths below you. Panic grips you as you see what looks like a large submarine in the inky depths below.
