Fe+C = Steel?

SITE SPECIFIC
OUTDOOR
ALL-FEMALE CAST

Here we are at Tai Kwun (former Central Police Station Compound, Central Magistracy and Victoria Prison Compound),
looking up at the big mango tree on the former prison yard under the night sky.
Metal wastes are of not much worth, and are often discarded ruthlessly or recycled. No one needs metal wastes. For fear of becoming metal wastes, they use up all efforts to break through layers of the robust wall, with unfaltering determination to transform themselves into steel.
Among all, how many have willingly chosen to face the thousand rounds of challenges? And how many will eventually transform into steel?
