The death of his wife brought the life of detective Adrian (Tony Shalhoub) to the bottom. Soon after, Adrian, who was often in grief, suffered from obsessive-compulsive disorder. Obsessive-compulsive disorder made Adrian nowhere to stay in the police station, and soon he lost his job and became a vagrant.
In order to survive, Adrian must make money, and in this way, a private detective agency was established. Adrian hired nurse Sarona (Bitty Schram) to take care of his daily life, and relied on his excellent logical reasoning ability and unforgettable magical skills to solve bizarre cases one after another. After that, Adrian met a single mother named Natalie (Traylor Howard), and the two fell in love with each other. With the passage of time, the pain of bereavement has faded from intense, but the causes and consequences of the murder of his wife are still hidden in the mist. Can Adrian rely on his own strength to solve this case and unravel the happy ending?
