The Mob Doctor

Spirits intensify at Roosevelt Medical Center when Dr. Devlin and Dr. Robinson treat a priest who was bitten in the face during an exorcism of a demon. After Constantine learns that newcomer Russell King has his eye on taking over downtown, he consults Celeste and Al Trapani to help him evaluate the risks and rewards of consolidating the power in Chicago. Meanwhile, Dr. Devlin dives deeper into the fold when Nate calls her into action to aide a runaway who may have witnessed a murder.

When a champagne bomb is delivered to Constantine, he and Celeste go on high alert to determine who wants him dead. Meanwhile, Nate turns to Grace after he accidentally jeopardizes a mobster's valuable racehorse. Back at Roosevelt Medical Center, Grace is tapped to treat Brett's estranged brother, Jack Hanson, following a severe cycling accident.

As Constantine attempts to reconnect with his estranged son Garrett, who is deep in debt to the ruthless Nogales Cartel, he enlists the help of his Chicago mob colleague, Al Trapani. As payback for the favor, Constantine orders Grace to diagnose Trapani's girlfriend, a patient with a shocking secret who is experiencing inexplicable pains.

Grace's world crumbles as her family remains in jeopardy, the FBI closes in and Constantine reveals something that rocks her to the core. Meanwhile, longtime mobster Al Trapani becomes increasingly involved in Constantine's business, and Franco's secret leaks. As the walls begin to close in on Grace and the duality of her life cuts deeper than ever before, she makes a desperate attempt to settle her role in both worlds.
