Pamela Drury (RACHEL GRIFFITHS) is a single, thirty-something writer whose many accolades and awards can't make up for the fact that she's unhappy and still wonders what her life had been like had she stayed with Robert Dickson (DAVID ROBERTS), a successful architect she hasn't been involved with for more than a dozen years.
Despite that successful and rewarding career, Pamela feels that she's wasted her life and is jealous of seeing just how happy her friend and mom, Terri (REBECCA FRITH), is with her life and family. Even when she meets someone she thinks she could be happy with, in this case Ben (SANDY WINTON), a high school counselor, she discovers that he has a wife and kids.
Even so, she gets the chance to see whether life is greener on the other side of the fence when an odd occurrence has her meet herself during a run-in with a car driven by her doppelganger. Dazed and returning with Pamela Two to her suburban home, Pamela thinks that she's dreaming of being married to Robert and mother to his three kids, teenager Stacey (YAEL STONE), her younger obnoxious brother, Douglas (SHAUN LOSEBY), and the still being potty-trained Rupert (TRENT SULLIVAN).
When Pamela Two suddenly disappears, however, Pamela realizes she must play the part of herself had her life turned out this way. As such, she must figure out the daily routines of this new, other life, as well as her job as a contributing writer for Now Woman Magazine writing "how to keep him satisfied" articles for her pushy boss, Deirdre (CHRISTINE STEPHEN-DALY).
As she realizes that her dream life isn't all that it's cut out to be, and has various run-ins with people from her "other" life, including Ben and married friends Geoff (FELIX WILLIAMSON) and Janine (ANN BURBROOK), all who think she's Pamela Two, Pamela must come to grips with the facets of her new life and try to make everything right once again.
