Smugglers Dungeon Escape

It was a lovely morning and you had gone out to the forest to do fishing in the stream that ran across the forest. The chirping of the birds, the crystal clear water in the stream and the absence of the city chaos was very soothing. Suddenly you overheard some people discussing some sort of plan. You went close to see who they were but just them the leader of the group saw you and kidnapped you. They were smugglers and they have put you inside their secret hideout. They have left you locked inside and this is the only time you have to try and escape from there. Think and act smartly.
