Stated plan

Capture the undefended knight on h1 with the rook for a free piece.

Reasoning

The black knight on h1 is undefended (the h4 queen's view along the h-file is blocked by White's own h2 pawn), and White's rook on f1 has a clear path along the first rank (f1-g1-h1) to capture it for free, winning material without any risk.
