An organisation known as Shadowspire kidnapped an A.R.G.U.S. agent before infiltrating the base and killing Amanda Waller (Cynthia Addai-Robinson) when she wouldn’t give them the access codes to a project known as Rubicon. With Lyla (Audrey Marie Anderson) also being held by Shadowspire, Diggle and Andy joined forces to save the day.
Elsewhere in the episode Felicity (Emily Bett Rickards) returned home and struggled to adapt to life as a paraplegic. Suffering from hallucinations, Felicity tried to keep it together so she could assist Oliver (Stephen Amell) and the team.
The next episode of the season is Unchained. Team Arrow receives a blast from the past when Roy Harper returns with an explosive plan. Plus, technical genius The Calculator threatens Star City.
