And with ingenious tactics, a pair of false teeth and a wheelchair each, they plot to outwit the security system at one of the casinos. As their antics become more and more daring, Martha and her friends head back to Sweden to continue their money-making schemes. However, they aren't the only ones planning on stealing bucket loads of cash and soon find themselves pitted against a gang of dangerous criminals.
