Watch Fifth Harmony's Post-Apocalyptic 'That's My Girl' Video

Fifth Harmony's 7/27 opener "That's My Girl" was previously an anthem for the U.S. women's gymnastics team ahead of the Rio Olympics, and now the empowering single gets another push with a cinematic new video.

In the Hannah Lux Davis-directed clip inspired by Mad Max, the girls bring out their inner hero as they help injured survivors suffering in a post-apocalyptic nation. 5H, rocking tattered black-and-white outfits, also show off their fierce dance moves as they're saving the world (which is shaped like a 5, of course).
