A family struggles for survival in a world where most humans have been killed by blind but noise-sensitive creatures. They are forced to communicate in sign language to keep the creatures at bay.
Marty McFly, a 17-year-old high school student, is accidentally sent 30 years into the past in a time-traveling DeLorean invented by his close friend, the maverick scientist Doc Brown.
Stranded in 1955, Marty McFly learns about the death of Doc Brown in 1885 and must travel back in time to save him. With no fuel readily available for the DeLorean, the two must figure how to escape the Old West before Emmett is murdered.
