[1] In the episode, the Broflovski family is dealt a devastating blow when Ike's Canadian birth parents show up unexpectedly, and want their baby back.
When the townspeople decide to forgo Christmas gifts and take up a collection to get Ike home to South Park, the boys are distraught.
Harry justifies their right to change their mind about putting Ike up for adoption as, due to a new law made by the Prime Minister of Canada, all Canadian-born children living in America must be returned to their biological parents.
South Park's citizens decide to act kindly towards the Broflovskis and agree to give them their Christmas gift money to help fund their legal battle over the Canadian Prime Minister, leaving their children without any presents: which Cartman blames on Kyle.
Traveling to Ottawa on the "only road" in Canada, the boys meet others plagued by the new Prime Minister's laws: such as a Mountie named Rick, who is forced to ride a sheep instead of a horse; an unnamed French Canadian mime, who can no longer drink wine; and a Newfoundlander named Steve, who can no longer practice sodomy.
In the Centre Block of the Parliament Buildings, the boys ask for a guard to let them in, but he insists the Prime Minister sees nobody and slams the door.
The boys finally meet with the Prime Minister, a gigantic floating head who is a brutal dictator and refuses to repeal his laws.
