Following his fall from grace in London and a stint in rehab, eccentric Sherlock escapes to Manhattan where his wealthy father forces him to live with his worst nightmare – a sober companion, Dr. Watson. A successful surgeon until she lost a patient and her license three years ago, Watson views her current job as another opportunity to help people, as well as paying a penance. Holmes resumes his work as a police consultant in New York City and Watson has no choice but to accompany her irascible new charge on his jobs. But Sherlock finds her medical background helpful, and Watson realizes she has a knack for playing investigator. With the mischievous Sherlock Holmes now running free in New York solving crimes, it’s simple deduction that he’s going to need someone to keep him grounded, and it’s elementary that it’s a job for Watson.
In season seven, Holmes and Watson’s new careers as consultants for Scotland Yard are disrupted by news that a member of their inner circle has been gravely wounded in the United States. As Holmes’ stateside legal trouble – the result of a confession to a murder he didn’t commit – threatens to keep them from returning to New York, their greatest foe to date, tech billionaire Odin Reichenbach, waits on the horizon to test their limits.
