Her youngest sister Alice, a private tutor, had missed two sessions with one of her students and the student’s parent was concerned.
Grace immediately reached out to her other siblings. Turned out, no one had heard from Alice for a couple of weeks.
The family called for a welfare check on her apartment, and officers found something concerning: Alice had moved out half a year earlier. No one knew her new address.
As Alice’s siblings started to search for her, they uncovered a secret life, a new man, and a mysterious trip across the world…
