Forcing mate in 28 moves

Stockfish 10 analyzed this game.
At one point it found a forcing mate in 28 moves. (I know that I had better moves before in the game)
So the question: Is there a forcing mate in 28 moves? And how does it look like:

I suggest that you play from that position against stockfish level 8 and post the game here.

It is in fact a mate in 16: 32. ... Qf3+ 33.Kd2 e3+ 34.fxe3 Rg2+ 35.Kd3 Rxe3+ 36.Kc4 Rxe1 37.Kb4 Qc3+ 38.Ka3 a6 39.Qc4 Qxa5+ 40.Qa4 Qxa4+ 41.Kxa4 Rxc1 42.Ka3 Rcxc2 43.Ka4 d3 44.Kb4 d2 45.Ka4 d1Q 46.Kb4 Rg4+ 47.Ka3 Qa1+

When Stockfish reports a mate, especially a long one like a mate in 28, it should be taken as "mate in x or less" rather than "mate in x". It just means that Stockfish has found a mate, not necessarily the shortest one.
