When we last saw Rose, she was practising coming out to dad - but will she? Does she have the courage? Inside she knows it's time. But how will dad react if she does? Coming out can be the scariest thing a lesbian, gay, bisexual, transgender, queer or questioning teen will ever go through.

A teenage girl and her single father. Rose is coming of age, and coming out of the closet. Dad wants to make sure Rose's coming out is as easy and painless as possible. Sometimes he tries a little too hard.

Season 3 plunges the clone sisterhood into unexpected territory with the realization that they're not alone. Just when they thought they knew their enemies and allies, season 3 reveals our clones are more vulnerable than ever before. Highly trained, identical male-soldiers raise more questions than answers. Who are these new clones? Who created them? And more importantly, why do they exist? Sarah, Cosima, Alison and Helena are stronger together than they are apart, but this season will put that bond to the test. Will they forge towards their truth, or fall at the feet of those who seek to control them?

Sarah is in a desperate race to find her missing daughter, but her scorched earth tactics spark a war with Rachel, dividing and imperiling all the clones. As Sarah discovers more about her past, mysterious newcomers appear, but can they be trusted?

Sarah is a streetwise outsider, currently on the run from a bad relationship and painfully separated from her own daughter. When an eerily lookalike stranger commits a shocking suicide right in front of her, Sarah sees a potential solution to all her problems by assuming the dead woman's identity and clearing out her bank account. But instead, she stumbles headlong into a kaleidoscopic thriller mystery, and soon uncovers an earth-shattering secret: she is a clone. As Sarah searches for answers, she soon learns there are more like her out there, genetically identical individuals, nurtured in wildly different circumstances. And someone is trying to kill them off, one by one.
