ELEMENTARY stars Jonny Lee Miller as detective Sherlock Holmes and Lucy Liu as Dr. Joan Watson in a modern-day drama about a crime-solving duo that cracks the NYPD’s most impossible cases. 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. However, the restless Sherlock is nothing like her previous clients. He informs her that none of her expertise as an addiction specialist applies to him and he’s devised his own post-rehab regimen – resuming his work as a police consultant in New York City. Watson has no choice but to accompany her irascible new charge on his jobs.
