Dave Allenson, a gruff security guard, is no fan of football, but he takes his job seriously. When, in the 1997 play-off against Iran, Peter Hore tries to tear down the net of the Iranian goal, Dave tackles him and prevents the vandalism - setting off a series of events in an alternate timeline of Australian football.

In this alternative universe 'sliding-doors' narration, we follow a pivoted history where the results of the infamous game between Australia and Iran had gone differently.

One tiny moment can change everything. Through the eyes of various players, associates, and others over the course of twenty years, this book traces the course of "what if".

What would Australian football and the National Soccer League have looked like if things were different?

It's just one version of how, if that moment had gone differently, things would be today.
