"If all the world's a stage..."

Enter Girl, protagonist, in belted shift, book in hand.
Lights fade up, spot follows Girl as she crosses down right.
Girl leans on right proscenium, reads as lights dim.
Spot on Girl and down left as Boy enters, also in belted shift.
Girl sees Boy, puts down book, and runs to meet him down center stage.
Long embrace, kiss as spot comes up on upstage right, as Man, antagonist, enters slowly.
Boy half skips off down left, mouthing promise to Girl of a swift return.
Man crosses down center, sneaking up on girl, pushing her to the stage right beam of the proscenium.
Man fumbles around, gleam in eye, as he prepares to do terrible things to Girl (left to audience imagination). Girl writhes and cries out in distress.
Spot up on Boy entering downstage left with picnic basket. He stands in shock for a millisecond at the sight of what is happening down right.
Boy pulls bottle from basket, breaks it. Man, hearing breaking glass, turns down left, flips up switchblade. Both slowly cross to center stage. Spots follow.
Boy, all nobility, raises arm in dramatic pre-strike pose. Man stabs Boy under arm.
Spot turns red, as Boy falls. Bottleneck rolls downstage right from hand.
Man pauses, watches Boy for a moment. Girl slowly picks up bottle.
Man turns downstage right, turning on girl, who hides the bottle fragment behind her back.
Man gradually breaks into run, pursuing the Girl with intent to ravage her.
Man gets ready to come down on Girl; Girl squirms.
Girl quickly reveals broken glass, and stabs the Man on the first thrust.
Beat.
Man staggers backwards to downstage center, tripping on the Boy. He falls, and will not get up.
Beat.
Girl slides down stage right proscenium beam, sobbing alone. Lights fade to black.
