After one of their sexual experiments in a happy marriage, Bob Palko is brought into hospital by wife Maria with symptoms that indicate a serious allergy. Tests, however, for the source all fail. While Foreman keeps whining about his lupus theory, House insists on tests for heavy metal poisoning; his prime suspect being Maria. Bob develops a number of other frightening symptoms, including heart failure, which viral cures don't solve. House gives Dr. Wilson, who is getting divorced, marching orders after a day for no reason. House also diagnoses Vincent Lambert with herpes, but neither he nor his wife Charlotte accept that they are to blame; House outsmarts them.
