Arrow: Lost in the Flood Synopsis Released

The CW has released the official synopsis for "Lost in the Flood," the upcoming, twenty-second episode of Arrow's fourth season, set to air on May 18.

Glen Winter directed the episode written by Brian Ford Sullivan & Oscar Balderrama.

Like every penultimate episode of Arrow so far, the episode is named after a Bruce Springsteen song. Season one's second-to-last episode was named after Springsteen's "Darkness on the Edge of Town," followed by "Streets of Fire," "This Is Your Sword," and now "Lost in the Flood." Another Springsteen song, "The Promise," shares a title with an Arrow episode but since it's a fairly general title and since it wasn't a penultimate episode, it isn't clear whether that was an intentional homage as well.

Following the shocking events in the previous episode, Oliver (Stephen Amell) and Diggle (David Ramsey) race to rescue Thea (Willa Holland), while Felicity (Emily Bett Rickards), Curtis (Echo Kellum) and Noah (guest star Tom Amandes) join together to stop Darhk (guest star Neal McDonough).
