  Summary

  The DeLorean crashed, it's 1885. Marty and Doc realize that radiation has leaked from the flux capacitor and that the car is now inoperable... unfortunately, they've already been irradiated.
  After spending more than 9 months in the Old West, Marty suddenly finds himself back in 1955, realizing he's traveled back in time without a time machine. Could Marty's new ability be the consequence of his altered biology?

  Unintentionally crossing time, he will require the Doc Emmett Brown's help to master this new ability, trying to get back to 1885 to save his best friend from that tragic death he found out while in 1955, even if it means gambling with the timeline by befriending the scientist in each era he ends up in...
