Mr. & Mrs. To (Lau & Cheng) are a divorced couple, they both affluent HK citizens,both incredibly mischievous and both just happened to be professional thieves.
A couple years earlier, they divorced over an inability to find middle ground on splitting the loot. Now she's remarrying to the son of a rich heiress -- a total momma's boy (Carl Ng) through & through. The soon-to-be mother-in-law (Jenny Woo) is suspicious of Mrs. To's past & thinks she's only marrying her son for the family jewels -- the heiress' priceless ruby necklace.
