Derrick stared at the red button. Jagged pieces of melted plastic stuck out at odd angles from the surface and sides. The button sat under a clear case, cut from some discarded item, the purpose long forgotten, which was tied down with a piece of old copper wire. Smudges of grease and dirt dotted the cover. Behind him, a clock on the wall with bright red numbers counted down from ten minutes. At zero, Derrick would have a ninety-second window to press the button. Ninety seconds to go home.
