Thirty-something Daniel Addison is jaded and burned out from his Parliament Hill job as a speech writer for the Liberal Leader of the Opposition. After a messy breakup with his girlfriend, Daniel is eager to escape the duplicitous world of Canadian politics, so he accepts a faculty position with the University of Ottawa's English Department. He soon moves into a boathouse apartment in nearby Cumberland owned by Angus McLintock, a cranky engineering professor in his sixties who is mourning the recent loss of his wife.

Both Angus and Daniel intend to retreat from the world for a while, but fate won't have it. Angus is desperate to avoid teaching English to first-year engineering students yet again. Daniel, as penance for abandoning his party on the eve of an election, must find a Liberal candidate to run in ultra-Conservative Cumberland. In an unlikely alliance, Angus consents to stand as the in-name-only, certain-to-lose Liberal candidate, and Daniel agrees to take Angus's English class.

Everything is going according to plan until the voters are suddenly forced to take a closer look at Angus, throwing his certain defeat into doubt. Scrambling to deal with this unexpected development, Angus and Daniel land in the middle of a hilarious political maelstrom that tests not only their friendship but their beliefs in government and democracy.
