As Blunt explains in the trailer (above) Warner Bros. released on Tuesday, the two accidentally “hijacked” the aliens’ power to relive the same day over and over again — which allows the invaders to figure out humanity's greatest weaknesses.

Using the newfound ability to wake up after death, the soldiers fight repeateedly through the same suicidal mission in hopes of discovering the secret to defeating their extraterrestrial enemy.

“Edge of Tomorrow” hits theaters on June 6.
