Beat 1 – Exposition
We meet the protagonist Marty McFly, a fun-loving teenager living in 1985 California with less than inspiring siblings and parents – his mother is an alcoholic, and his father is bullied by his boss, Biff, a main antagonist. An aspiring rock musician, Marty likes playing guitar, skateboarding, seeing his girlfriend Jennifer, and helping out his close friend Doc Brown, an eccentric scientist and inventor. That night, Marty heads to the mall to assist Doc, who says he has made a major breakthrough.
Beat 2 – Inciting Incident
When Doc reveals he has transformed a DeLorean car into a time machine, Marty’s ordinary world is shattered. After successfully testing it, Doc shares it is powered by plutonium, which he stole from Libyan terrorists. As he prepares to travel into the future, the Libyans arrive, seeking revenge. Doc is shot and killed.
Beat 3 – Plot Point 1
Marty jumps into the DeLorean to escape, and a car chase ensues. As the DeLorean speeds up, it suddenly disappears, and Marty is transported 30 years back in time to 1955. After crashing into a barn, Marty hides the now dysfunctional time machine and wanders into town, bewildered by the new world he has entered.
