Ep 17. Duet

When Barry Allen (the Flash) and his team come up against a metahuman capable of manipulating reality through her singing, they find themselves in a difficult position. After she puts both Iris and Mon-El into comas, they turn to the only person they know who has any experience with singing villains - Barry's old friend and ally, Music Meister.

Music Meister teleports himself into the team's headquarters, but things quickly take a dark turn when he uses his powers to put both Barry and Kara Danvers (Supergirl) into comas of their own. The two find themselves trapped in a dream-like world that takes the form of a 1940s-style musical.

The episode unfolds as a classic Hollywood-style musical, complete with song and dance numbers, elaborate costumes, and colorful sets. The plot follows the love story of Barry and Kara, as they move through various musical numbers, each designed to teach them something about themselves.

As they work their way through the dream world, they realize that they need to work together to defeat Music Meister and return to their respective realities. Along the way, they meet a number of familiar faces from the DC universe, including Malcolm Merlyn, Winn Schott, and Joe West.

Throughout the episode, the two heroes confront their own fears and insecurities, learning to rely on each other and their friends in new ways. As the fate of the real world hangs in the balance, they must use their combined strength to overcome Music Meister and restore everything to normal.

The episode is a departure from the usual tone of The Flash, opting instead for a lighthearted and whimsical approach. It's a fun and playful tribute to classic musicals, packed with humor, romance, and catchy songs. Although it doesn't advance the show's overarching plot, it's a welcome break from the norm that showcases the talents of the cast in a unique and enjoyable way.
