Colonel Thomas Bushell of the Royal American Mounted Police leads the search for the painting, accompanied by its former curator Dr. Kathleen Flannery and Captain Samuel Stanley. Some days later, a ransom note is received from the Sons of Liberty. The Governor-General of the North American Union, Sir Martin Luther King, informs Bushell in confidence that the painting must be recovered before King-Emperor Charles III's state visit, or the government will have to pay the Sons' ransom demand of fifty million pounds.
