After experiencing a bloody storm with intensive gunfire again, Barney (Sylvester Stallone), Christmas (Jason Statham), Gunnar (Dolph Lundgren), Billy (Liam Hemsworth), Turnpike (Randy Couture) and Caesar (Terry Crews), the Expendables, are enjoying the rare comfort after the war. But the good times didn't last long. One night, Church (Bruce Willis) came to the door and forced him to go to the Gazak Mountains in Albania to find a safe on a shot down plane and ensure that the box would not fall into the hands of the enemy.

This is no longer a task, but a war about the friendship and honor of the soldiers...
