Among the dry, barren lands of Afghanistan in 2010, a war is raging. Five Australian soldiers have embarked on a dangerous and unsanctioned mission to find their missing comrades. But in the dead of night, they suddenly find themselves ambushed.
Bombs explode around them and the Taliban fighters let loose a hail of bullets from afar. Amid the deafening gunfire and dense blanket of smoke, Captain Ted Nordenfelt (Ewen Leslie) orders his unit to retreat.
The men scramble to safety as another explosive detonates. But as the men withdraw, one of their own loses his life.
When the soldiers return home, there's one question on everyone's lips: how did the mission go so wrong?
That's the intriguing premise of new Aussie drama, Fighting Season, where the gravity of war, and what really happened one fateful day, will haunt the men long after they've come home.
In the first episode, team leader Sergeant Sean "Speedo" Collins (Jay Ryan), Corporal Peter "Pepsi" Aboud (Julian Maroun) and privates Jarrod Vogel (George Pullar) and Isara'elu "Izzy" Uleli (Marco Alosio) arrive in Australia.
They're welcomed as heroes. But as they mourn the loss of a friend, it becomes apparent there's more to the story than the men are letting on.
Sergeant Collins insists the soldiers get their stories straight, leading viewers to believe he has something to hide. Jay hints the "unravelling of events" will cause tension among the troops and propel them to the depths of despair.
"The soldiers live in army housing, so everyone is incredibly close," Jay, 37, tells TV WEEK. "The soldier was our neighbour, friend and confidante. So it becomes very complicated and the events go well beyond just a military death."
Meanwhile, Izzy, still injured and "able to remember only snippets of what happened", is struggling to agree with the story of events. He knows someone is lying – but who?
Izzy isn't the only one who suspects a cover-up. Ted's wife Kim (Kate Mulvany) senses something isn't being said.
"When she hears whispers of a conspiracy, she tries to work out exactly what happened and who is to blame," Kate, 40, explains.
For Sean, the harrowing experience is compounded by his fractured home life. His wife Vanessa (Sarah Armanious) and their son Zac (Zack Grech) are struggling to adjust to his return.
"Every time Sean comes home, there's always a transition period where he has to get back into family life," Jay explains.
"That's the first jolt. Then the trauma of the war begins to surface and it gets incredibly hard for them."
Sarah adds that, despite all efforts, their connection is waning.
"When we meet Vanessa, she's struggling to take the reins when Sean is on deployment, and then having to share them when he's back," she says. "She also wants him to let her in."
Elsewhere, Jarrod and Pepsi attempt to stow away their pain by partying and making reckless decisions.
But as the returned servicemen adapt to normal life back in Australia, the questions of who they are, who they can trust and what really happened will torment them.
Is the enemy among them?
