The movie picks up exactly where the previous film, The Force Awakens, left off, with Rey finally finding Luke Skywalker and handing him his father’s lightsaber.
It’s one of the stranger touches in Star Wars: The Last Jedi.
Luke’s white robes are ceremonial Jedi apparel that are part of the ritual of burning down the [ancient Jedi] tree.
