Get ready for an adventure.

"The Handmaid's Tale" star Joseph Fiennes has signed on to accompany his cousin, the legendary adventurer Sir Ranulph Fiennes, on a quite a journey. The two will head down the Nile River in Egypt for an upcoming three-part National Geographic docuseries, Deadline reports. Called "Fiennes: Return to the Nile," It's a homecoming of sorts for Ranulph, who first explored the area 50 years ago, early in his career.

It should be exciting. The Fiennes cousins will both be put to the test. Joseph will be trying to hack it as an adventurer for the first time, while Joseph will be recreating a trip five decades after the fact. Nat Geo has teased that they'll face tombs and frightening creatures.

In spite of the challenges, Joseph, who is also producing, said that he is "delighted to be embarking on this adventure" with Nat Geo and Ranulph. "It is every boy's dream to go on an expedition with the world's great living explorer," he added.

We can all follow along from a safe distance. The three-part docuseries will premiere in 2019.
