The Exception 2016

Early in the film there is a scene with a girl in her slip or possibly her nightie, pale blue with lace trim. She is wrapping a handgun in a piece of cloth. We don't get to see that it is the lovely Lily James but later events make certain that it was.
Still early in the film Lily has her first scene with Jai Courtney, he tells her to take her clothes off and she does. Who would have thought it was that easy? This is a disappointment though, beneath her dress she isn't even wearing a bra let alone a slip.
Later in the film she is in Courtney's room, they've done the deed and she starts to dress, pulling a shortish black fullslip over her head.
