Denny Finch begrudgingly arrives in the country town of Wonthaggi where his extended family awaits aboard a minibus, ready to transport him to the nearby town of Leongatha for his cousin Darryl's wedding.

The gang depart Wonthaggi en route to Cape Paterson to pick up the marriage celebrant where the trip is delayed further upon Denny's grandmother revealing her wishes to spread their dead grandfather's ashes at a nearby beach.

The clock is ticking as the bus stops one more time to pick up members of the bride's family but before long one of them is missing and the rest of the gang are sent out to search for her.

The search for Mary has been called off but things go from bad to worse when Darryl takes the wheel and promptly runs over a local "wombat".

After a narrow escape from the law the bus to Leongatha keeps rolling but not for long as it finally comes to a sputtering halt, leaving Denny and the gang stranded in the middle of nowhere.

After a long and arduous journey, the gang finally make it to Leongatha, but is it too little too late for Darryl & Carol?
