The official synopsis reads:
Oliver (Stephen Amell), Arsenal (Colton Haynes) and Diggle (David Ramsey) track down the location of a boomerang-wielding killer named Digger Harkness (guest star) but are surprised when they come face to face with an A.R.G.U.S. team. Diggle asks Lyla (guest star) why A.R.G.U.S. is involved but she defers until Harkness attacks the building, killing several agents and targeting Lyla. The Arrow joins the fight and gets help from an old friend - The Flash (guest star Grant Gustin). Harkness manages to get away and Oliver teams up with Barry again to find him before he can get to Lyla. When Harkness plants five bombs in the city that are timed to explode at the same time, both teams must come together to save the city.
The crossover event kicked off with The Flash episode 8 titled, Flash vs Arrow, where the lightning bolt fought the green Arrow in an epic showdown.
