Stated plan

Capture the undefended rook on e8 with the queen.

Reasoning

White's queen on a8 attacks the rook on e8 along the open eighth rank (b8, c8, d8 are all empty), and the bishop on f8 does not defend e8 diagonally. Capturing wins a full rook for free with no compensation, since the black king on c6 is far from the action.
