One night two urchins, who live near the Bombay docks, go looking for their lost cat amongst the many ships. One of them is very scared, the other adventurous. They come across a very strange-looking ship. When they go exploring, they find chests full of treasure. But a boat inside a bottle catches their eye. As they hold on to it the boat inside the bottle sways as does the ship the boys are in. On the bottle is written: ''Sinbad the Sailor received this on his last and seventh voyage''.
