Spirits are always high at the quayside pub The Red Rabbit. One day, adventurers Pat and Patachon come by to look for work. Their luck is in! A police raid sends all the staff to prison. On the spur of the moment, two women from the upper-middle class decide to study the life of the common people by paying them a visit. A brawl ensues, and Pat and Patachon chivalrously bring the two women to safety – or so they think! Before they know it, all four end up aboard a steamer in the pitch black of night, on their way to new adventures and unknown, dangerous shores.
