Jacob is an alcoholic reporter, his estranged cousin Isaac is a worldly photojournalist just recently returned to Canada-and their editor pairs them up to cover a story on Parliament Hill. The problems start when Jacob vomits onto the Prime Minister, an act which is mistaken for an assassination attempt. While in jail, the cousins get information which sends them on a madcap romp to try and track down what might be the story of their lives, involving a government coverup, an international fugitive and a lesbian love nest in the Northern Ontario woods.

When their car breaks down, stranding them in the woods in the middle of the night, Jacob and Isaac finally face up to their painful shared past, and come to terms with what has divided them for all these years.

Thunderstick has been produced in Toronto, Winnipeg, Saskatoon, and Edmonton, where it drew standing-room-only crowds. One paper described the characters as 'an aboriginal Oscar and Felix.'
