Julia Roberts is Running Wild for a good cause.

The Oscar winner will be partnering up with Bear Grylls for the upcoming NBC Red Nose Day three-hour special to raise awareness of life-saving vaccines. Roberts and Grylls will travel to Kenya and traverse hazardous terrain to deliver the vaccines to a remote village — all under a time limit.

The two must navigate dense underbrush and avoid the wildlife — like crocodiles and hippos — as they race to the village while having to keep the vaccines cold.

And that’s just one part of the three-hour extravaganza airing May 25 on NBC. In the exclusive video above, Chris Hardwick reveals that he will be hosting the special as he breaks down the jam-packed schedule planned for the night.

The evening will then wrap up with Hardwick hosting the Red Nose Day Special at 10 p.m. Roberts will also appear during the third hour as she visits Africa as part of a short film.

To end the night, Hardwick will host the one-hour special featuring the buzzed-about Love Actually reunion titled Red Nose Day Actually.
