I mean the details and context are different, but the major plot points in TFA borrow a ton from Star Wars.

-Droid has crucial information that needs to be delivered to Rebellion which is also be relentlessly pursued by the Empire

-Droid finds its way into the custody of our main character, the catalyst which starts the protagonists adventure.

-Protagonist meets an older, wiser “father figure” who used to be involved in with the rebellion, who upon learning of the information contained within the droid offers to help deliver to the rebellion.

-Protagonists learn of the existence of a planet-killing superweapon that poses great threat.

-A covert rescue operation is attempted inside the superweapon in which older “father figure” is killed followed by an Rebel assault on the super weapon(in TFA these things happen simultaneously)

There are a ton of story and character differences of course in TFA which I think makes it distinct enough to stand on its own. Plus the climactic saber battle and the ending with Luke on the island set the ending apart as well. But for a good majority of the movie, the narrative thrust which gets our characters from point A to B to C are driven by the same sort of plot devices as in Star Wars. The movie is derivative, but I think is saved in the characters and the details.
