Stated plan

Relocate the knight from the attacked d7 square to the safe, active c5 square, dodging the Rxd7+ threat.

Reasoning

White's main threat is Rd6xd7+, winning the undefended knight with check (the bishop on g7 is safe since Rxg7+ Kxg7 loses a rook for a bishop for White). I need to move the knight to safety while keeping activity. Nd7-c5 is a safe square (not attacked by any white piece) and pressures the e4 pawn, avoiding loss of material.
