Late at night, several people prepare to smash a single protective layer inside a guarded room but argue about timing because guards and dummy figures on the bed could give them away. They decide to wait for a passing train at 10:08 p.m. to mask the sound. As the train arrives they count down—three, two, one—and smash the layer. After a tense pause one voice says, "Enough." Then someone adds, "It worked." They break through, but whether the noise or the dummies will still alert the guards remains unresolved.
