Back to the Past

To save tomorrow, they must survive yesterday.

A time-travel action-comedy that blends historical epic with sci-fi intrigue, pivoting on a fraught reunion between a reclusive inventor and the emperor he once mentored.

In the Qin Dynasty, time-traveller Hong Siu-lung has lived in seclusion with his family for twenty years. Yet every step he takes remains under the watchful eye of his former disciple, now the Qin Emperor. On the brink of ultimate power after conquering the six warring states, the emperor is suddenly ambushed by a mysterious team wielding advanced weapons clearly originating from Hong’s time. Drawn together by fate again, Hong and Qin Emperor are forced to confront the long-buried conflict between them, because the future now depends on how they settle their past.
