The Invisible Man (2000) : 1x16

Darien, the Keeper and Hobbes head south of the border to Santa Ruego to convince the Prime Minister to vote against installing the Biox chemical weapon system. How? By having Fawkes pretend to be a ghost and persuade the superstitious Minister to vote against the system's installation. Unfortunately, another ""spirit"" is haunting the Minister: ""La Llarona,"" a ghost who can drown men with a kiss. She confronts Darien and it is revealed she is a member of a shadowy organization that bio-engineered her with the ability to breathe water and exhale it under pressure. In the battle over the Prime Minister's vote, Darien eventually manages to drive her off and get the vote, despite the mutual attraction the two ""freaks"" share.
