When does Pekín Express return?

Peking Express is a Dutch–Flemish reality game show that follows a series of couples as they hitchhike to or from Beijing. The theme of the show is to demonstrate how various couples deal with the challenges and pitfalls of attempting a long-distance hitchhiking to a strange city. The music used during the opening sequence is "Summon the Worms" from Brian Tyler's soundtrack to the 2003 miniseries Frank Herbert's Children of Dune.
