The short version
Back to the Future follows Marty McFly after Doc Brown's DeLorean time machine accidentally sends him from 1985 to 1955. Marty interrupts the moment when his parents, George and Lorraine, were supposed to connect, creating a threat to his own existence. He finds the younger Doc and works on a plan to harness lightning to return home, while also trying to make George brave enough to win Lorraine's affection. Marty's actions change his parents' confidence and the family he returns to. The final scene sends him toward another time problem involving his future children.

The ending is satisfying because Marty fixes the immediate timeline while changing what his family believes about itself. George's courage in 1955 reshapes the adult household in 1985, making the time-travel plot a story about confidence and consequence. The final interruption by Doc keeps the adventure moving, but the emotional payoff is seeing Marty return to a family no longer trapped by the same old fears.
