"Arrow" Targets HIVE in Plot Synopsis for Midseason Finale "Dark Waters"

The CW has released the plot synopsis for the "Arrow" midseason finale, "Dark Waters," and it looks like Oliver (Stephen Amell) is taking the fight to HIVE -- though that may not be the best idea, as it's said Damien Darhk (Neal McDonough) will retaliate in a "brutal manner" at Oliver's holiday party. Sounds like a very unhappy holiday season for Team Arrow -- here's the official description:

OLIVER TAKES ON HIVE - After the city is attacked again, Oliver (Stephen Amell) makes a bold move against HIVE. Malcolm (John Barrowman) checks in on Thea (Willa Holland) and leaves her with a warning. Things take a horrible turn when Damien Darhk (guest star Neal McDonough) retaliates in a brutal manner at Oliver's mayoral holiday party. John Behring directed the episode written by Wendy Mericle & Ben Sokolowski (#409).

"Dark Waters," the ninth episode of "Arrow" season four, airs 8 p.m. on Wednesday, Dec. 9 on The CW.
