Ver en Cuevana. An exceptional museum in Sweden houses the Vasa sailboat – a ship that has been lifted out from the bottom of the sea where it ended up after an unfortunate maiden voyage. One day, the museum staff notice a rat in the boat’s hull and begin setting traps to catch the rodent before it damages this brilliant museum piece; however, as it turns out, the rat is not alone. In fact, there are surprisingly many of them. The staffs’ attempts to get rid of the rodents prove futile. And, because of its gentle Swedish upbringing, even the cat they bring in doesn’t help. They need to call in the experts – the Rescue Team!
