Four Corners

How the Liberal Party tore itself apart.

This Four Corners investigation takes you inside a political catastrophe.

We chart the rise and fall of Malcolm Turnbull and the enemies that stalked him from within.

Steve Bannon's new world disorder.

"This revolution is global. It's coming to Australia." Steve Bannon

As the Liberal Party tries to piece itself back together after the chaos of last week, Four Corners brings you an interview with the man hoping to overthrow the entire political class.

"I think that Australia is going to be a hotbed of populism."

Steve Bannon put Donald Trump in the White House and rewrote the rules of modern politics along the way. Described as the most dangerous political operative in America, the strategist, renegade Republican and professional provocateur channelled the anger and disappointment of those who felt left behind by globalism to install Donald Trump as president.

"There's a lot of anger out there and I think that this anger can be harnessed."

Now, he's taking his cause to the world in a crusade to "save" western civilisation, as the leader of a global populist-nationalist movement. He calls it a revolution.

"Populism is about getting decision making away from a set of kind of global elites...and get it back to working class people."

In an age of upheaval, he sees opportunity. After playing a key role in Britain's Brexit campaign, he's been forging links with right wing nationalist groups across Europe, including the French National Front.

Australia is next on his radar. He's identified Australia as ripe for his brand of revolution and plans to bring it here.

"Australia is at the tip of the spear on this."

In an interview with Sarah Ferguson, Bannon outlines his manifesto for change and why it resonates with people around the world.

"It doesn't matter how many liberal journalists come in here and say 'Oh this is a bunch of fascists, this is a bunch of Nazis, this is a bunch of racists.' This... is not going to stop." Steve Bannon

Tonight Four Corners screens the BBC report, "Manchester Bomb: Our Story" on the teenage survivors rebuilding their lives from May 2017.

"My main present for Christmas last year was my Ariana Grande ticket…I'd never been to a concert before, so we were absolutely buzzing!" Caitlin

They were young girls and teenagers, on a night out to see their favourite pop star. Many were attending a concert, without their parents for the first time.

"Everything was just really exciting, really, it was new." Izzy

As the show ended, a terrorist detonated a home-made bomb packed with shrapnel.

"There was, like, music playing while we got up and I was just making my way out onto the stairs and then we heard, like, a boom sound." Niamh

22 people were killed, more than 250 injured and countless lives were impacted.

"We ran, and we were running for our lives. We didn't know what the hell was going to happen next." Charlotte

Filmed over many months, this program tells the story of several young survivors as they, and their families try to reclaim their lives.

"She wears a mask that to the outside world, she's fine. She's really not fine…People see this bright, bubbly, carefree girl, and I just think she wears this mask so well that sometimes she fools herself." Erin's mum

Some are able to return to their old routines, but in the privacy of their bedrooms, the girls reveal their struggles.

"It's times when you kind of let your guard down a little bit and you try and enjoy yourself and then you feel guilty for feeling that way and you feel guilty for getting on with your life when other people can't." Niamh

Despite their darker days, some are trying to find inspiration for the future.

"It's kind of made me realise like life is short and I want to do stuff and I want to get out there." Amelia

Who Cares? "They're all someone's mum, someone's dad."

A special two-part investigation of the failings in aged care.

"They're all someone's mum, someone's dad, someone's brother, someone's sister. They were all young once and they're just forgotten." Senior aged care consultant, NSW

On Monday Four Corners launches the first of a two-part special investigation into the treatment of the elderly in aged care homes.

"I was a personal carer in an aged care facility and I'm speaking out because people need to know what it's really like in a nursing home." Aged care worker, NSW

In the ABC's biggest crowd sourced investigation, we asked our audience to share with us their experiences of the aged care industry. More than 4,000 responded.

"I'm speaking up today for people that don't have a voice." Senior aged care consultant, Victoria

Many of those who have come forward are professionals who have extensive experience in the industry and are concerned by what they have seen.

"I believe our elderly deserve to have better care." Senior aged care consultant, NSW

In part one of this investigation, Four Corners examines the business of aged care and what that means for the vulnerable residents left in its care.

"When they go into have a look at a facility, they do see the glamour. They might see a sing along or a coffee club or something like that. They see the glitzy pictures and they don't know about the ground level care." Diversional therapist, Victoria

Families have also decided to speak out, with disturbing accounts of overworked staff and neglected residents.

"Within three weeks, she was no longer the person that she had been. Nan would never want to complain about things and when I was there I would verbally bring up things with the staff. No resolution was ever evident. And so I started filming it." Granddaughter

With families and aged care workers from around the country, Four Corners reveals the shameful lack of care and dignity experienced by many elderly Australians.
