No release date yet

Alan leads the charge at a packed meeting of subpostmasters to persuade the JFSA to finally push for their day in court - the legal costs are enormous and they may end up with no financial compensation even if they win, but they all agree to pursue the truth at any cost. Up against the might of the Post Office and its legal team, Alan and the JFSA must once again fight to prove their own honesty, and this time it is in the highest court in the land. They must produce the evidence needed to persuade a judge to side with them over a Government-owned and much-loved national institution, but the powerful testimony of a whistleblower could be enough to get them over the line.

Alan and the JFSA take their fight to the top of the Post Office as CEO Paula Vennells offers them the chance to apply for compensation for their losses. New JFSA member and former schoolteacher Pam Stubbs is one of the first to apply for the mediation scheme, but help may have come too late for Martin Griffiths as he is pursued by the Post Office for massive alleged shortfalls of 60,000 pounds. Mediation led by lifelong Post Office employee Angela van den Bogerd proves slow and bureaucratic, so Alan seeks help from James Arbuthnot MP in holding the Post Office to account. However, when Alan hears some shocking news from within the JFSA and faces huge personal challenges, he begins to lose hope for the first time in 12 long years.

When a new computer system called Horizon is installed across the country, mysterious financial losses start to appear in village Post Office tills, but when subpostmasters Alan Bates, Jo Hamilton, Noel Thomas and Lee Castleton seek help, the Post Office insists that each of them is the only one having such problems. Alan, who is stubborn and computer-literate, refuses to put it behind him and is sure that he will one day find the evidence to prove the Post Office is wrong, and when the Post Office goes on to accuse, harass, and even prosecute the subpostmasters for the shortfalls, Alan leads their fight back.
