The girlfriend and model of a well-known Maastricht artist is found dead in her parents' bathtub, with a plastic bag over her head. Everything points to suicide, but her father, a former police officer, is convinced it is murder. The case takes Wolfs and Eva into a world of art, big egos, jealousy, and lots of alcohol and drugs. Then they discover that the dead girl in the bathtub is not the only model who has died under suspicious circumstances. Are they dealing with a serial killer? Marion meets an old school friend at the police station. They hit it off right away, until she hears what he's there to report: aliens have abducted his favorite cow. Laughingly, she promises to take a look at the farm, where Romeo loses count among the cows and Marion thinks there's more to it than that.
