Stated plan

Play Qf3-e4+, exploiting the pawn-protected check to drive the king into a cramped square and continue the attack.

Reasoning

The black queen can jump to e4 with check, and this square is protected by the black pawn on d5, so the white king cannot capture. Checking all king escape squares shows only c3 is safe (c4 is covered by the pawn and queen, c5 by the knight on d7, d3 and e5 by the queen, e3 by the queen's file). This forces the king to c3, after which Black can continue the attack, e.g. picking off the knight on c2 with check, winning material and keeping the white king exposed.
