When Daisy hears that NYPD's newest and most promising detective, Riley Wolfe, has taken a particular interest in hunting her down, she will pull out all the stops to ensure her own continued survival. That includes going undercover as Detective Wolfe's newest room mate.

Zen "Jersey" Sinatra is an outspoken, wild, and spontaneous individual. She talks a bunch of shit, and has a pack of friends to back it up for her. Zen is one of the biggest tattoo artists in Los Angeles. She owns her own tattoo shop that never has a slow day. Most would say that Zen is living the life. She lives in a penthouse suite (paid by her ex-mafia affiliated father), owns her own business, and can get any girl she likes. The only thing Zen is committed to is her job, her friends, and her family. Never has Zen been in a committed relationship, and she believes she never will. Well, that's until a troubled Finley Wood shows up.
