The world fell into a pandemic when it was announced that a deadly virus is spreading throughout the world. All countries were sent into an immediate lockdown to prevent further spread of the disease. Little did it help. As the virus spread to more and more countries, more people became diseased and soon only half of the world population was left. Continuar, a highly classified organisation that made themselves known as the pandemic grew, created a safe space for those fortunate enough to gain access to it. Those who didn't were left to die. But unfortunately, nothing is ever as it seems. Katharina Bythesea wakes up from a coma after 5 months. She meets a guy called Edmund Sheng. After she is released from the hospital, she gets taken in by the Bythesea family. She starts to work as a scientist's assistant at the Continuar laboratory. Little did she know that she would encounter her past there. On her mission to uncover her past and save the world out of the clutches of Continuar, Edmund joins her on her journey along with the help of her new family members. But what will she do when they uncover her secret? Will Katharina be the salvation of the world or be its destruction?
