It’s a quiet rainy evening at a 24-hour flower shop, and the mild-mannered clerk Freddie lays out mousetraps around the store to stop an evasive vermin that has been eating all the merchandise. At the same time, he gets anxious when his favorite regular customer, Mrs. Calloway, a quirky but loving old woman doesn’t arrive to pick up her arrangement on schedule. Passionate about his customers and the shop, Freddie must protect the flowers while dealing with the critter and the increasingly unusual people that come by at these strange hours.
