For more on what to expect from this episode of Supergirl, here’s the recently released synopsis courtesy of The CW:
Kara (Melissa Benoist) is moved by the story of a missing woman named Izzy (guest star Harley Quinn Smith) and decides to investigate despite Snapper Carr’s (guest star Ian Gomez) order to leave it alone. Kara takes Mon-El (Chris Wood) with her to the last place Izzy was seen and the duo find themselves thrust through a portal to another planet, Slaver’s Moon, where the downtrodden are sold as slaves. The leader of the trafficking ring is none other than Roulette (guest star Dichen Lachman).
To make matters worse, Slaver’s Moon has a red sun, which means Kara and Mon-El are stripped of their powers and stuck on the planet with no way home. Meanwhile, back on Earth, Alex (Chyler Leigh) blames herself for Kara’s disappearance, fearing she’s become too focused on her new relationship with Maggie (guest star Floriana Lima) and too complacent in watching out for her sister. Kevin Smith directed the episode with story by Andrew Kreisberg and teleplay by Eric Carrasco & Jess Kardos.
Supergirl has been doing well since it moved from CBS to The CW, something which was reflected by the fact that the network recently renewed the series for a third season. Seeing Kara Danvers enter Roulette’s fight club was already a ton of fun when it was on Earth, but placing the action on an alien planet where the hero is rendered powerless should be even better.
Smith brought a lot to the table in the Scarlet Speedster’s world and should be able to do the same with this upcoming episode of Supergirl, making it a must-watch and what will no doubt be a great way to kick off the second half of the season.
