Stated plan

Capture the undefended rook on f2 with the queen, winning material.

Reasoning

The white rook on f2 is undefended (the bishop on g2 only covers diagonals f1/h1/f3/h3, not f2, and the king on h2 is not adjacent to f2). Black's queen on h4 can reach f2 via the h4-g3-f2 diagonal, capturing the rook for free without allowing recapture.
