We've had a few sneaky peeks at the big alien invasion event that is bringing together Supergirl, Legends of Tomorrow, Arrow and Flash at the end of the month, but the CW just released new extended synopses for the event, giving us some intriguing details about how it all comes together.
The four synopses for each episode essentially confirm a lot of things we knew already -- mainly that the episode of Supergirl launching the crossover wouldn't really focus on the crossover until the end of the episode, and that really the actual smackdown against the alien dominators won't actually happen until that week's episode of Legends. Here's Supergirl's synopsis, which promises Thanksgiving drama:
Eliza (guest star Helen Slater) comes to town to celebrate Thanksgiving with her daughters. Alex (Chyler Leigh) decides it's time to come out to her mother; Kara (Melisa Benoist) is shocked when Eliza suggests Mon-El (Chris Wood) has feelings for her, and Winn (Jeremy Jordan) and James (Mehcad Brooks) consider telling Kara the truth about the Guardian. Meanwhile, CADMUS unleashes a virus that instantly kills any alien in the vicinity so Kara enlists an unexpected ally -- Lena Luthor (Katie McGrath). The epic superhero crossover kicks off tonight when Barry Allen (guest star Grant Gustin) and Cisco Ramon (guest star Carlos Valdes) seek Kara's help with an alien invasion on their Earth.
Then The Flash, which seems like it will interrupt crossover goodness to remind us that Barry is still a goddamn mess who screwed up the timeline:
When aliens called the Dominators attack Central City, Barry (Grant Gustin) speeds over to Star City to ask the Green Arrow (guest star Stephen Amell) for help in stopping them. Realising the battle against the Dominators is bigger than they thought, they track down the Legends of Tomorrow, and Barry and Cisco (Carlos Valdes) create a breach to bring back a secret weapon -- Supergirl (guest star Melissa Benoist). Once all of the super friends are assembled, they come up with a plan to attack but a shocking secret related to Flashpoint is revealed and suddenly no one is sure who they can trust. Meanwhile, Wally (Keiynan Lonsdale) wants to join the battle against the aliens but Iris (Candice Patton) tells him he's not ready.
Here's Arrow, which is also the show's 100th episode -- and seemingly the one least connected to the crossover while it deals with its own bit of timeline weirdness:
Oliver (Stephen Amell) wakes up to a life where he never got on The Queen's Gambit. Robert (guest star Jamey Sheridan) and Moira Queen (guest star Susanna Thompson) are alive and well. Laurel (guest star Katie Cassidy) is his loving fiancée and their wedding is imminent. Everything seems perfect, but Oliver starts to notice small imperfections that make him question this new reality. Meanwhile, Felicity (Emily Bett Rickards) and the recruits take on a new threat with help from The Flash (guest star Grant Gustin) and Supergirl (guest star Melissa Benoist).
And finally the big throwdown itself in Legends:
After learning the Dominators' plan for the world, the Legends must work together with The Flash (guest star Grant Gustin), Supergirl (guest star Melissa Benoist) and Green Arrow (guest star Stephen Amell) to kill them once and for all. Meanwhile, Stein (Victor Garber) figures out, with the help of others, how the team can terminate the Dominators, but is distracted by the aberration he realises he created in 1987.
This is gonna be fun! The crossover beings with Supergirl on November 29.
