After Slade (Manu Bennett) threatens to take everything Oliver (Stephen Amell) loves away, Oliver decides the fastest way to stop further bloodshed is to surrender to his enemy. Knowing that surrender will surely lead to Oliver's death, Diggle (David Ramsey) and Felicity (Emily Bett Rickards) go to extreme measures to keep Oliver from confronting Slade. Meanwhile, Thea (Willa Holland) considers leaving town, and Laurel (Katie Cassidy) resumes her crusade against Sebastian Blood (guest star Kevin Alejandro). Finally, Slade unleashes his assault on Starling City.
