The Dark Hand in Rome releases the Water Demon. Jackie and Uncle chase after her with the Chi Spell, while she escapes to Valmont's hide out. There she learns of the San Francisco Vault and plans to use it to flood the city while Valmont wanted Shendu out of his body because of all the grueling activities that Shendu is doing to his external features. When he knocks out Shendu, he consults Jackie and the team to help him get rid of Shendu. Jackie, Valmont, Jade, and Tohru discover that she was casting a spell in the subway system after Valmont exposed all that he knew. Uncle has the Chi Spell and a spell to rid of floods, but not a spell to rid Valmont of Shendu. Valmont helps Jackie fight the Water Demon so Uncle can eliminate the flood, but both demons escape.
