Tomorrow Was a Long Time Ago

In the year 2176, a consortium of the world's greatest scientists has created a device that allows people to travel in time. One member of the consortium goes back in time to change his family's fortune, regardless of who else it affects.

Meanwhile, ASD (assassin detective) Trang Lieu is enjoying life with her loving husband and two little girls—until the Director of Investigations asks her to look into a major crime committed more than 130 years ago. She doesn't want to do it, but she has to. The nature of the crime means the very existence of her family may be at stake. 

The problem is, Trang only gets one shot to fix things, and she has to do it quickly or something worse may occur.
