Stranded in 1955 because he couldn't do one simple thing, Marty McFly learns about the death of Doc Brown in 1885 and must travel back in time to save him even though everyone and their hot mom in high-school knows it's a bad idea. With no fuel or cocaine readily available for the DeLorean, the two must figure how to escape the Old West before Emmett is murdered by a dude who spits more than he talks. Jennifer wakes up on her front porch and is incredibly (and rightfully) confused.
