Den of Thieves 2: Pantera is the upcoming sequel to 2018's Den of Thieves, a heist movie that tells the story of 'Big' Nick O'Brien (Gerard Butler) and his unorthodox police crew as they attempt to track and apprehend a sophisticated criminal gang led by Merriman (Pablo Schreiber). The first movie's climax reveals that the character of Donnie (O'Shea Jackson Jr.), thought to be Big Nick's informant, was actually the mastermind behind Merriman's plans, so the sequel finds Nick hot on Donnie's heels in pursuit. However, for reasons unknown thus far, the two end up working on the same side of a new diamond heist.
