WATCH: The Girls Cast Unite To Deliver A Powerful Message On Sexual Assault

In the continued fallout from the rape case of Standford University’s Brock Turner, the ladies from HBO’s Girls have lent their voices to a growing campaign for the victims of sexual assault.

Lena Dunham, Allison Williams, Jemima Kirke and Zosia Mamet filmed a sexual assault PSA, with the women presenting some disturbing figures including that 1 in 5 girls are sexually assaulted in their lifetime, and 80 percent of cases perpetrated by somebody they already know.

“Why is our default reaction as a society to disbelieve, or to silence, or to shame?” said the actresses.

“What if we chose to turn toward those in need, instead of away?” asks Mamet.

Dunham tweeted the video out on Wednesday, dedicating it the survivor of the Standford case.

Watch the PSA below:

I dedicate this to the brave survivor in the Stanford case who has given so much to change the conversation. https://t.co/KMOJUxvPu0
