In Canada for a conference, Ironside and the team get caught up in a spate of bombings, courtesy of Quebec separatists; one of them the son of an old girlfriend of the Chief's. When one of the bombings proves fatal, Ironside suspects that there is more going on than just terrorism; and he soon links the killing to a famous stolen chess set.
