From the show:

Morgaine Gooding-Silverwood’s "Stone" honors Leslie and other overlooked butch heroes of the 1960s. The inter-generational piece is a devised work of historical fiction based on the very real legacy of butch solidarity and gay community organizing that took place as a response to the police violence and anti-crossdressing ordinances of the era. Stone is an homage, a celebration, a love letter and a reflection.
