Stated plan

Capture the undefended g4 pawn with the king to win material.

Reasoning

The black king on g3 can simply capture the undefended g4 pawn, since neither White rook nor pawn structure defends it. This wins material safely while the black king remains reasonably secure, and lines like Rh8h1+ only lead to an even rook trade after Ke2 (f2 is covered by the c5-bishop), so grabbing the free pawn is the most concrete gain.
