Dec Donnelly is forced to take part in a life-threatening stunt on tonight's Britain's Got Talent.
The presenter is visibly shaking with fear as he's called up on stage by spooky performers Brotherhood.
The daredevil group, who are wearing black suits and some very creepy masks, are tempting fate with their dangerous trick and put their lives in Dec's hands.
After chopping a watermelon in half with a samurai sword, they decide to play a game of mystery in front of the worried judges.
Simon Cowell looks very concerned when Brotherhood reveal the sword will be hidden under one of four cardboard boxes.
BGT's Army vet: 'I served my queen for 25 years — now I want to sing for her'
They will each fall onto three of the boxes, without knowing whether they will be skewered.
Stunned Simon looks from side to side in shock, while Amanda Holden lets out a giggle.
Dec is called up on stage and gets a helpful push from pal Ant McPartlin before being asked to decide where the sword goes.
Brotherhood say: "Our lives are in your hands."
Dumbfounded Dec recoils in horror as he's handed the sword and realises he could be responsible for a nasty accident.
After confirming he will have the power, Brotherhood add: "As it's series 13, choose wisely."
A black screen goes up so no one except Dec knows where the sword has been placed.
Simon chooses which boxes they will fall on top of by picking envelopes out containing the numbers.
Ant turns to nervous Dec and says: "It's best you don't watch this."
Brotherhood then risk their lives by taking it in turns to fall and jump on top of the boxes.
Will they be landing on a cardboard box or a sharp samurai sword?
And if they are still standing at the end, will they make it through to the next round?
*Britain's Got Talent airs tonight on ITV at 8pm
