Stated plan

Attack the black queen with the rook, forcing it to move or be captured favorably, while the rook is defended by the bishop.

Reasoning

Black's queen on c2 attacks the bishop on d2. By playing Rf1-c1, White attacks the queen along the c-file while the rook is defended by the bishop on d2 (diagonal d2-c1). If Black captures Qxc1, White simply recaptures Bxc1, winning the queen for a rook. Otherwise the queen must retreat, saving the bishop.
