Chloe, Dan, and Lucifer investigate a young woman's dead body found discarded in the woods. The woman has a triangle-shaped stamp on her wrist which becomes a key clue when they find another female victim with the same stamp. With Chloe depressed over her pending divorce, Maze, Dr. Martin, and Ella take her to a bar for girls night. Chloe sees a man who has the triangle stamp on his wrist and soon learns the stamp comes from an underground sex club. They discover a man named Yuri had a connection to both victims and photos on his phone help them find the killer. Elsewhere, Charlotte struggles to adjust to her domestic life, while Amenadiel agonizes over his diminishing angelic powers. He then learns of Lucifer's deal with God: return Charlotte to Hell in exchange for sparing Chloe's life. Amenadiel says Lucifer's punishment of Charlotte does not fulfill the deal and wonders if God will take back his half of the bargain. Just then, Chloe is shown driving when a car smashes into hers.
