In the scandalous and scintillating fourth season of "Vanderpump Rules," Lisa Vanderpump and her sexy current and former SUR staffers find that as everyone grows up, their triumphs, failures, makeups and breakups have only gotten bigger -- and badder. This season, Lisa is joined once again by Jax Taylor, Scheana Shay, Tom Sandoval, Ariana Madix, Katie Maloney, Tom Schwartz and Kristen Doute, along with James Kennedy. On a mission to keep SUR one of the hottest restaurants in Los Angeles, Lisa is faced with the ongoing challenge of controlling her disorderly bartenders, servers, hostesses and bussers. Jax is trying -- and failing -- to overcome his impulsive nature and stay on his best behavior for his new girlfriend(s), while Kristen’s troubles with boyfriend James land her in uncharted relationship waters. Meanwhile, as Tom Sandoval and Ariana’s relationship grows deeper, some of their closest friendships shatter. For Katie and Tom Schwartz, a big step forward in their relationship involves a ring without a string, but first they must deal with the lingering issues between them. Newly married, Scheana quickly begins to fear her marriage may be on the rocks when she learns her husband has been keeping secrets. To top it off, the group’s world is turned upside down when a major player from their past re-emerges to settle unresolved scores.
