The three cards

 Their backs were against the uprights in the old barn basement.  Their arms were up above their heads.  Their wrists were pulled behind the uprights, crossed and tied with strong rope.  Around their biceps the ropes lashed their upper arms to the uprights, as well as their necks.

Their feet were pulled behind like their wrists, ankles crossed and roped.  Rope around their thighs lashed them to it, like the ropes on their biceps.

Old rags were stuffed into their mouths, covered with a knotted bandanna, gagging them.

Sweat poured from their faces and armpits.  Their shirts drenched with sweat.

The camera was placed so their torsos, circled with ropes, and their faces were in view.  Another camera was behind their heads, showing the rope that secured their biceps.  A metal bar was put between the ropes, and turned, tightening the ropes around their upper arms and the upright, cutting deep into their strong muscle.

The camera in front zoomed in on their faces.  eyes popping out in terror... gagged grunts and moans coming from deep in side them from the torture.

Their shirts were torn open, exposing their roped bare chests and bellies.

A number was drown with a wide sharpie between their pecs....

1-2-3

Three cards were shuffled.

Put face down.

The metal bar between their upper arms was now placed in the ropes around their necks.

"Mr. Benson.  You have 1 hours to deposit the ransom.  Or we draw a card and you will watch one of your sons choked slowly to death."

They put a timer next to the cards.

Left the bound brothers struggling to get free.

Staring at the three cards.
