Thorn is being treated at a Metropolis hospital for gunshot wounds, wounds given her by a Metropolis police officer, so Black Canary and Huntress guard the officers guarding Thorn. They encounter John Mercado, one of Thorn's allies on the police force and an enemy of the 100, but this encounter allows some of the rotten officers to spirit Thorn away. Meanwhile, Oracle discovers an unknown, dangerous entity within her virtual data sources. Canary, Huntress and Mercado trail the officers and apprehend them, but Thorn gets away.
