Four girls, one mic, and lots of drama.

When Mariposa (aka MC Patria) meets Ezekiel Matthews (aka MC EZ1) they quickly become best friends; together they have the best summer tossing lyrics and rhymes. After the summer ends, Mariposa realizes the only thing she really cares about—besides becoming the best emcee around—is getting Ezekiel to love her. Unfortunately, this realization comes at the same time Ezekiel gets a girlfriend—Jennifer Hoffman (aka J-Ho 5), an emcee with a huge buzz.

When her school announces a talent show, Mariposa understands that this could be her last chance to impress Ezekiel. She decides to form a hip-hop crew—enter the world of the Sista Hood—MC Patria, Soul Siren, Pinay-1, and DJ Esa, all divas in their own way. While coming together isn't easy, they're forced to collaborate and their lives are changed forever.
