Stated plan

Capture the undefended knight on e5 with the knight from f3, winning material.

Reasoning

The knight on e5 is undefended by any black piece (bishop c5 covers d6/d4, not e5; knight f6 doesn't defend e5; queen b6 is on a different diagonal). Capturing it with the f3 knight wins a piece for free, since Bd6 is adequately defended by the queen on d2 along the d-file if Black tries Bxd6 in response.
