Following the events of The Last Jedi, Rey struggles to let go of her lonely childhood on the desert planet of Jakku. Hoping to have a breakthrough in her Jedi training, she returns to her home world with Finn and BB-8 in tow. When they meet a young girl on a dangerous mission to save her family, they travel through pitch-black tunnels beneath the sand where they encounter scurrying gnaw-jaws, a haunting terror from the past, and maybe—just maybe—hope for them all.
