What do a green-eyed cat, a garden filled with aromatic herbs and wind chimes inside an abandoned house, have in common? A teenage girl, Miriam, has the chance to find out during the pitch-black night of "Earth Day". The movements of the cat, the different scents of the plants and the wind chimes entice Miriam in, but first she must brace herself and draw enough courage to pass beyond the rusted gate. What was meant to be a night-time walk of no more than 300m became an adventure and discovery.
