"The Loneliest Planet" will keep viewers questioning the nature of human relationships. Julia Loktev's mysterious and quiet love story, which claimed the Grand Jury Prize at AFI Fest, follows a young engaged couple, Nica (Hani Furstenberg) and Alex (Gael García Bernal), as they travel throughout the Caucasus Mountains in Georgia with a local guide the summer before they marry, TheWrap said.

Everything goes swimmingly at first, until a small gesture is made that makes the couple question everything they thought they knew about each other.

The film comes out Oct. 26.
