Stated plan
Capture the queen with the knight, exploiting the mutual attack to come out ahead in material.
Reasoning
The knight on g4 attacks the white queen on e3, while White's bishop on e6 simultaneously attacks Black's queen on c7 - a mutual queen attack. Since it's Black to move, Nxe3 wins the queen first. If White recaptures with fxe3, Black's queen simply retreats, netting a queen for a knight. If White instead plays Bxc7, the black knight on e3 forks the rook on f1 (and other squares), regaining material and leaving Black clearly ahead. Either way, Nxe3 is winning material.
