Yesterday Once More

In Hong Kong, a married pair of jewel thieves, Mr. To (Andy Lau) and Mrs. To (Sammi Cheng Sau-man), part ways soon after a diamond heist that went smoothly, with no reason either one gives. A year on, she is engaged to the son of a rich woman and about to sign a pre-nup so she can wear a family heirloom. Johnnie To keeps the two circling each other, still the only ones who understand how the other works.
