This is a pair of eccentric metal detection enthusiasts who walk day after day through field trails and open fields, stepping through dirt renovated ridges.They have an almost obsessive expectation in their hearts - they hope that one day, the buzzing of the detector can break the dullness of ordinary life and bring amazing discoveries to change their destiny.In this seemingly boring search, every time you bend over, it is a question of the unknown and a close approach to your dream.
