Official Promo for “Supergirl” S02E20 “City of Lost Children”

The CW has released the official trailer for the 20th episode of Season 2 of “Supergirl”.

Titled “City of Lost Children”, this episode is scheduled to air on The CW in the USA on Monday, May 8 at 8.00pm ET/PT.


When an alien attacks National City, Supergirl (Melissa Benoist) and the DEO learn the alien is a Phorian, an otherwise peaceful race with telekinetic powers. Guardian (Mehcad Brooks) gets a lead on the Phorian’s address but instead of finding the culprit, he finds a very scared boy named Marcus (guest star Lonnie Chavis). Marcus will only trust James so it is up to Guardian to stop the attacks on the city. Rhea’s (Teri Hatcher) plan escalates.

The episode was directed by Ben Bray from a story by Robert Rovner and teleplay by Gabriel Llanas & Anna Musky-Goldwyn.
