One hundred years ago, the recurring conflicts between the Bader and the Dorset ended mysteriously when both races colonized the distant planet Delta Sigma IV – a world located far from the destructive wars of their people – and quickly became the Federation's perfect example of interspecies cooperation. But there are now rumblings of trouble in paradise, as an investigation led by Kyle Riker – Commander William Riker's estranged father – into this harmonious society has discovered a shocking, immutable truth: over the next few generations, the reaction to a native gas will spell the extinction of Delta Sigma IV's inhabitants. Captain Picard and his crew, still recovering from the tragic events that have tarnished the career of one of the Federation's most decorated captains, must come to the aid of a world that once knew only peace, but now faces emerging violence and chaos…and Commander Riker must confront the reality that his own father may be held responsible for Delta Sigma IV's almost certain downfall!
The recurring blood feuds between the Bader and the Dorset ended mysteriously a century ago when both races colonized the planet Delta Sigma IV. But, unknown until now, it was a reaction to a naturally occurring gas that led to their harmonious existence… a reaction that would eventually mean certain death for the planet's inhabitants. What the Enterprise crew believed was a cure for the population – a treatment introduced into Delta Sigma IV's environment by Kyle Riker, a man at odds with his son, Commander William Riker – has instead triggered worldwide carnage, as long-suppressed aggression and hostility are suddenly and violently unleashed. Caught in a world on the brink of self-destruction, Captain Picard – a man still waging his own personal battle for redemption in the eyes of his commanding officers – must somehow find a way to resolve this catastrophic event and save his crew, even as the implications of his actions may ultimately doom an entire race…
At the height of the Dominion War and unknown to all save those in the highest levels of command, the Federation secretly armed the neutral planet Tezwa with devastating weapons – part of a contingency plan against the Dominion if the front lines collapsed. But Tezwa also lies near the border of the Klingon Empire… making the Federation's covert strategy in direct violation of their fragile peace treaties, and creating the potential threat of scandal and all-out war. Now Tezwa's power-hungry prime minister is all too eager to flex his newfound military muscle, menacing a nearby Klingon border world. Sent on an urgent diplomatic mission, Captain Picard and the Enterprise crew are caught in the crossfire as the crisis quickly escalates. With time running out and billions of lives at stake, only one man can avert the looming disaster – Ambassador Worf, who must choose between his oath to the Federation and his loyalty to Martok, Chancellor of the Klingon Empire…
A cataclysmic war between the Federation and the Klingon Empire has been miraculously averted, and a new government is finally in place on the planet Tezwa. But deadly secrets still threaten the fragile peace accord. Rebels still loyal to the old Tezwa regime have captured Commander Riker and are willing to kill to achieve their goals… the Orion Syndicate is interfering in the rebuilding – and may also be involved in much more than that. But the most devastating revelation of all threatens the very foundations of the Federation itself – leaving Captain Picard to possibly face the very conflict that he labored so hard to prevent…
Following the scandalous Tezwa affair, the Federation president's resignation forces an election, with the future of the United Federation of Planets to be determined by who emerges victorious from a hotly contested vote. But it is the fate of the entire galaxy that may actually be decided on Qo'noS, as the Federation embassy is seized by terrorists whose actions expose intrigue reaching the highest levels of Klingon government – and it will take all of Ambassador Worf's skills to keep the fragile Federation-Klingon alliance from collapsing. And while this potential intergalactic chaos looms, Commander Riker finds his plans for command and marriage soured by a brutal, high-level inspection of the ship from which the crew may not escape unscathed… The epic miniseries comes to a shocking conclusion – one that will leave the Star Trek universe changed forever!
