Disc is tapped in on the sideline. Horizontal stack is set as normal.
Cutter 2 initiates deep toward the force sideline.
Cutter 3 also cuts deep toward the force sideline. Cutter 4 then makes a slash cut toward the middle of the field.
This is the first viable throw in this set play.
If it is not thrown...
Cutter 4 continues to the break side, clearing hard. Cutter 2 cuts into the vacated open side for a long open under pass.
This is the primary option.
If it is not thrown...
Cutter 2 clears out toward the break side. Cutter 1 gives a deep option. Cutter 3 also begins to clear toward the break rail, being wary that he or she may need to be the next cut.
Classic 2 dump upiine or backfield reset: Handler B makes an upline cut. Handler A sets up for an around throw. Cutter 4 takes Handler A's former position.
From here the thrower can throw upline, around to the new middle handler for a swing, or huck to cutter 1. Notice how cutter 1 has plenty of space to make an under cut after handler B gets the disc upline.
