A recent video showing a group of people swimming through a sewage tunnel has gone viral, attracting widespread public attention and sparking curiosity. Posted on Instagram by Gnarly Charlie, the video shows an adventurous and risky escapade that took a dramatic turn.

In the footage, Charlie, his friend and his girlfriend embark on a daring adventure on a rainy day. Equipped with inflatable boats and protective wetsuits, they explore a dark and winding sewer tunnel. Charlie's friends enter the tunnel first and disappear into the darkness. As Charlie and his girlfriend follow them, they are immediately caught in a tidal wave. Due to the force of the current, their boat quickly fills with water and they realize they have been separated from their friends.
