Stated plan

Force the exposed white king further into the open with a rook check along the d-file, setting up a winning attack.

Reasoning

White's king is dangerously exposed on d4. Black's rook can deliver a powerful discovered-style check along the d-file, since d5-d7 are empty. After Rd8+, White's king has essentially only Ke3 as a legal escape (other squares are covered by the bishop on b7, the b6 pawn, or the queen's control of the c-file), driving the king into an even more exposed position where Black's queen, bishop, and knight combine for a decisive follow-up attack.
