Stated plan

Move the bishop from e5 to d4 to escape the rook's attack while staying active.

Reasoning

The bishop on e5 is attacked by the rook on e4 along the e-file, and nothing defends it. It must move to safety without losing material or tempo. Bd4 retreats to a safe central square, keeping the bishop active and away from attack.
