Alex (Chyler Leigh) teams up with Detective Maggie Sawyer (Floriana Lima) to investigate the case while Kara searches for a recently escaped Mon-El (Chris Wood), who she fears may be the alien behind the assault.

Tank Girl and Freddy's Dead: The Final Nightmare director Rachel Talalay, who recently helped the episode of The Flash titled "Fast Lane," directed the episode, which was written by Jessica Queller and Derek Simon.
