It's 1969 and NASA has launched Apollo 11 in hopes of landing on the moon. They also hope to transmit live images of the event back to Earth and have so employed a mammoth radio telescope in the rural town of Parkes, New South Wales, Australia as the backup dish to their prime receiver in California.
To make sure things go smoothly in their "just in case" scenario, NASA has sent a by-the-books representative, Al Burnett (PATRICK WARBURTON), to Parkes to make sure everything goes as planned.
There, he meets Cliff Buxton (SAM NEILL), the older team leader of what turns out to be the largest receiving dish in the Southern Hemisphere, along with his crew, Ross "Mitch" Mitchell (KEVIN HARRINGTON) - who doesn't think Al or NASA respects the Aussies - and Glenn Latham (TOM LONG). He's the shy calculations expert who can't find it in himself to ask out Janine Kellerman (ELIZA SZONERT), the young woman who repeatedly brings the crew snacks and is the sister to Rudi (TAYLER KANE), the dish's lone and overzealous security guard.
The townspeople of Parkes are just as excited as the team to be involved in such a historic event, and none could be prouder than Mayor Bob McIntyre (ROY BILLING). He's eagerly awaiting the arrival of both
Australia's Prime Minister (BILLE BROWN) and the United States Ambassador (JOHN McMARTIN) with whom he'll watch the landing, all while dealing with the varied reactions of his family members including wife May (GENEVIEVE MOOY), son Billy (CARL SNELL), and his moody teen daughter, Marie McIntyre (LENKA KRIPAC) who's the object of attention for Keith Morrison (MATTHEW MOORE), an overeager cadet in training.
As time counts down toward the scheduled landing and they suddenly find themselves as the primary receiving station for the big event, the Australian team must deal with various unforeseen complications and mishaps as they race to get things back in order to televise the footage around the world.
