The CW on Thursday has finally released the official plot synopses of the highly-awaited musical crossover of "The Flash" and "Supergirl."
The special crossover event, which kicks off on Supergirl's March 20th episode is titled "Star-Crossed." Per TV Line, here's how the network is describing the first part: "A new villain (guest star Teri Hatcher) comes to National City, putting Supergirl on high alert. Meanwhile, Winn's girlfriend, Lyra, gets Winn in trouble with the law. Maggie attempts to help Winn but old loyalties get in the way. The Music Meister attacks Supergirl."
The crossover will wrap up on The Flash's March 21st episode aptly titled "Duet." The episode's description reads: "Barry and team are surprised when Mon-El and Hank Henshaw arrive on their Earth carrying a comatose Supergirl who was whammied by the Music Meister. Unable to wake her up, they turn to Team Flash to save her. However, the Music Meister surprises The Flash and puts him in a similar coma, one that Team Flash can't cure. Kara and Barry wake up without their powers in an alternate reality where life is like a musical and the only way to escape is by following the script, complete with singing and dancing, to the end."
In addition to Grant Gustin and Melissa Benoist, the crossover will also feature musical performances from Jesse L. Martin (Joe), Victor Garber (Dr. Stein), John Barrowman (Malcolm Merlyn), Jeremy Jordan (Winn), Carlos Valdes (Cisco) and guest star Darren Criss (The Music Meister).
As previously reported, Gustin and Benoist will perform a duet of the song "Superfriends," written by Rachel Bloom (Crazy Ex-Girlfriend), while Gustin will do a solo of "Runnin' Home To You," by "La La Land" songwriters, Benj Pasek and Justin Paul.
The CW will air new episodes of "Supergirl" and "The Flash" on March 6th and 7th, respectively.
