'Nurse Jackie' Season Premiere: Consequences, Rock Bottom And A Whole New Direction

After three seasons in a freefall, "Nurse Jackie" (Sun., 9 p.m. ET on Showtime) finally hit her rock bottom on the fourth season premiere. The episode opened with Jackie -- sporting a longer hairdo -- checking into rehab, and apparently doing so voluntarily, albeit sullenly as well. How did she get to this point?

That's what the rest of the episode was about. Apparently, all it took was for her to take a look at her life and where all of her bad decisions have led her. For one, they led her to a church for prayer, where she met a fellow devotee, played by Green Day's Billie Joe Armstrong, who was rather aggressively in her personal space. Jackie apparently responds well to that sort of thing, because she took him home and they had a drug-filled good time, until it proved too much for Mr. Armstrong's character, and he dropped dead.

Eddie put the final nail in the coffin of Jackie's marriage by admitting to their affair to Jackie's husband Kevin. He then got a short and well-deserved beating for his role in everything that's gone wrong for the family. O'Hara, and ultimately Lenny and Zoey as well, helped Jackie take care of the dead guy problem in her apartment, after which Jackie finally had her moment of self-realization and decided she needed to get into rehab.

So that's where Jackie will be -- if she stays -- for the next 28 days, while the staff back at the hospital deals with the arrogant and incredibly blunt new man in charge. Now that they are part of a conglomerate, there are likely to be some changes, and Dr. Cruz (Bobby Cannavale) looks like he'll actually enjoy implementing them.

The new and completely different season of "Nurse Jackie" continues Sundays at 9 p.m. ET on Showtime.
