Kara must make it out of National City with a ticking time bomb in the latest clip from "How Does She Do It?", next week's episode of "Supergirl." In the video, Maxwell Lord (Peter Facinelli) puts the bomb in her care, as it has the power to level 30 city blocks. Kara immediately accepts the responsibility and books it out of National City as the detonation looms ever closer.

"Supergirl" airs Mondays at 8 pm EST on CBS. Developed by producers Greg Berlanti, Ali Adler and Andrew Kreisberg, the series stars Melissa Benoist, Calista Flockhart, David Harewood and Chyler Leigh.
