A woman's perfect life is shattered by the return of her estranged son, which reawakens a terrifying secret buried in her bloodline.

Developer Tsang Siu Chi and his agent have bought two of a group of four properties. Rival developer, Boss Hung has secured the other two properties. Both aim to buy all four so they can knock them down and build hotels.

Frustrated with his commitment-phobic boyfriend Chris and running out of time, Min makes a proposal: a green-card marriage with their friend Angela in exchange for her partner Lee's expensive IVF. Elopement plans are upended, however, when Min's grandmother surprises them with an extravagant Korean wedding banquet.

A group of old college friends reunite for a wedding. But after the banquet, a 15 year old girl shows up claiming that one of them is her father.
