USA's original series Graceland has gone a long way to raise awareness about human trafficking this season, and now the network is going one step further.

On Sunday, USA will air a 10-hour "End Human Trafficking" Law & Order: SVU marathon hosted by Graceland stars Daniel Sunjata and Serinda Swan, TVGuide.com has learned exclusively.

During the marathon, which kicks off Sunday at 1/Noon c, USA will partner with the United Nations Office on Drugs and Crime and Polaris, a leader in the global fight to eradicate modern slavery, to provide viewers with information and resources about this issue that impacts more than 20 million people worldwide.

Additionally, Sunjata and Swan will film a new PSA set to air during the Aug. 20 episode of Graceland encouraging viewers to donate to the UNODC's Trust Fund for victims of human trafficking. The PSA will coincide with the culmination of Graceland's ongoing human trafficking story line.

Graceland airs Wednesdays at 10/9c on USA. Will you be tuning in Sunday?
