A&E has debuted five new pieces of promo art for Bates Motel, the network's new original series that debuts Sunday, March 18 at 10 PM ET with the Season 1 Premiere. These posters offer more questions than answers, though, with handcuffed guests, severed body parts, and an intriguing image of what appears to be a crop of marijuana plants. Perhaps that is how Norma (Vera Farmiga) and Norman Bates (Freddie Highmore) really make their living.
