Mr. Black returns to duty when a dangerous escaped convict resurfaces in the city. The criminal underworld grows more complicated when a vengeful scientist enters the picture, harboring a dark grudge against those who wronged him. Together, the unlikely pair concocts a catastrophic scheme: they plan to round up innocent citizens and launch them into the void using an advanced space station called the Green Star. The operation is set to commence on the station's grand opening day, leaving authorities almost no time to respond. Mr. Black mobilizes every resource at his disposal, rallying fellow officers and recruiting an unlikely ally: a determined young pig cop with something to prove. What unfolds is a desperate race against the clock as the team works to dismantle the conspiracy before it can be executed. High-stakes action collides with sci-fi technology as Mr. Black confronts his enemies in a final confrontation aboard the Green Star itself. The fate of an entire city rests on whether he and his partners can stop the criminals' ambitions before they succeed.
