In a sandstorm, several notorious criminals in a prison in Southern Xinjiang took the opportunity to beat our public security officers and escaped. Among them, there is Ma Wanå¾·, a sinister "two-faced person" who can speak both Uighur and Chinese; there is "Potato Egg", a fugitive who swore deadly enmity against the public security officers; there is "Black Son", the original armory worker who is perverse and cruel and killed people out of revenge; there is also Bak, the principal offender of bank robbery who is naturally belligerent and extremely greedy.
