A drunken fight between parents saw their Kiwi mum drag Colin off to live in Wellington, while Don stayed at home with dad in Brisbane.
The pair are reunited as adults at the Basin Reserve in Wellington where they are put on trial by the very man responsible for their separation, Greg Chappell.
"The writers have done a great job of contrasting Colin against his big bulshy Australian brother," celebrated actor and former Hawke's Bay man Brougham says.
What results is a tumultuous ride through sport, politics; the ugly side of broken families and of course Aussie/Kiwi relations.
"The whole 'incident' is a sideshow to these guys who were separated at the game, spent their childhood apart and a lot of their adult lives apart.
Directed by highly-awarded actor/director Peter Hambleton it contrasts a nation's love of cricket with the emotional debate between brothers.
"It's a really gutsy drama, the sort of writing that will have [audiences] bowled over with laughter then quite tearful the next minute."
People will be transported back to the cricket ground where they play the part of an angry crowd.
"It's beautifully written, it's a see-saw ride at times. Audience members don't need to be mild-mannered and polite, they can engage as well."
