Assassination bid in Canada on the Russian Premier. Suspended from the Royal Canadian Mounted Police, Corporal Timothy Shavere (George Segal) is given a last chance by his commander (Denholm Elliott) with an assignment to safeguard Premier Alexei Kosygin during his visit to Vancouver. His mission is to confine a resident alien Rudolph Henke, who is on the KGB surveillance list. Henke's capture proves difficult and Shaver's future is on the line. The plot thickens when Shaver realises the KGB plan to assassinate the Russian premier on Canadian soil with a CIA bomb.
