She rents an apartment in a new apartment block but soon regrets the move as a neighbor tells her the apartment is haunted by the spirit of a young mother who threw her daughter out of the window before jumping to her death herself. A series of strange occurrences convince Lin there really is a ghost before the spirit finally reveals herself to Lin. The ghost tells Lin she too will one day commit murder/suicide in the same fashion.
