The I.M.P are invited to meet a mysterious figure offering them a vague job. Upon arrival, Moxxie realizes that he is far more familiar with the place and the figure than he'd like to be.

In an effort to watch Azathoth's tears descend onto Earth, an event that Stolas promised to take her to but forgot to, Octavia steals his grimoire from the I.M.P's office to do so but ends up getting lost in Hollywood.

Blitzø discovers that his reserved, sole parking spot has been stolen by his ex-girlfriend, succubus and famous pop star Verosika Mayday. He and the rest of the I.M.P attempt to get it back by challenging Verosika to a "demon duel."
