What Is HEART ATTACK (2025)?

In a chilling post-pandemic future, gene therapy has eradicated disease and saved humanity from extinction. But progress comes with a price. The treatment has spawned a new breed of humans called Variants—individuals blessed with extraordinary, unique powers that society fears and governments refuse to acknowledge. Strip away their superhuman abilities, and these Variants face a grim reality: the state has deemed them less than human, denying them basic rights and protections. This gripping premise explores themes of discrimination, identity, and survival in a world that sees difference as danger.
