Sisyphus: The Myth is JTBC’s 10th anniversary K-drama inspired by the Greek drama of the same name. It jumps between two timelines—future that has been ravaged by war and is in dire need of resources, and the present where Kang Seo-hae (Park Shin-hye) has traveled to, in order to stop Han Tae-sul (Cho Seung-woo) from creating a time machine. Han Tae-sul is in a mad rush to unveil the cause behind his older brother’s death. It turns out, these two timelines have a cause-effect relationship that is explored throughout the series.
