Stated plan

Give check with the knight while escaping the rook's attack.

Reasoning

The knight on a4 is attacked by the rook on a7. By playing Nc3+, Black gives check to the king on e4 while simultaneously moving the knight off the a-file, saving it from capture and forcing White's king to react.
