In a heart-surgery section a man and a woman are waiting for their open-heart surgery, promising each other to climb up a wall together shortly after the operation. A Challenge, a vow, a promise: their finish line is a Dolomites’ wall. Their will of achieving it provides them with energy and courage. Their finish line is their new starting line. It’s a sunny July day when they tie the rope to climb the wall to test their heart and to honour their promise.
