The final season of Strings of Darkness focuses on three storylines, which happen almost completely independently of each other, resolving the remaining plot threads after the fall of Cerberus. Tommy, Tapp, Tracy, William, Conan, Olivia and Ved join forces with Olly to put a stop to Raja's machinations once and for all. The path takes them to China, where Raja attempts to utilize the power of The Witch of Ao Kuang to revitalize his powers and take over the world. TT and his new gang, meanwhile, have to navigate shaky trust between them after their "hostile takeover", in order to locate and kill Seven before he finds a way to avenge the Cerberus. Far from all of this, in Moscow, Vasily and Chips have to overcome one final challenge to establish Vasily as the true kingpin of crime - defeat Yevgeni. This proves more difficult than expected after the lie Boris told Vasily turns out not to be a lie at all - Yevgeni is, in fact, the older son of Vasily's mother, Vika Sazkaljovich.
