Arin Kalay, Katharina's Kurdish apprentice, becomes a murder suspect when a dead body is found during a cooking exam at the vocational school. A corpse encased in concrete is discovered at the nursing home across from Katharina's restaurant "White Lily." Two murder cases that seem unrelated at first glance disrupt the daily routine at the "White Lily," forcing Katharina to once again use her refined culinary instincts as a detective. When she finally uncovers the connection between the two murders, she fears it may already be too late for Arin. A case for top chef Katharina Schweitzer: a spicy crime story, enriched with culinary elements and sensually garnished.
