The crawl to my edit attempts to set this stage somewhat:
Luke Skywalker has vanished.
In his absence, the sinister
FIRST ORDER has risen from
the ashes of the Empire and
will stop at nothing until
Skywalker, the last Jedi, has
been destroyed.As the peaceful New
Republic struggles to fight
this resurgent menace,
General Leia Organa gathers
her allies and leads a brave
RESISTANCE. She is
desperate to find her brother
Luke and restore hope to the
galaxy.
