Starring TV Week Gold Logie winner Asher Keddie as obstetrician Nina Proudman and AACTA Award winner Kat Stewart as her sister Billie, Offspring follows Nina's quest to manage the intensity of her job delivering babies along with the challenges of raising her daughter Zoe in the midst of the fabulously unpredictable Proudman family - all while trying to establish a decent love life for herself. Eighteen months after the events of series five, Nina has been in a relationship with dedicated midwife Leo (Patrick Brammall), who is a colleague of hers at St Francis. Billie has been managing husband Mick's (Eddie Perfect) tour in the UK and youngest sibling Jimmy (Richard Davies) runs his busy Mexican taqueria while his wife Zara (Jane Harber) undertakes the gruelling challenge of studying for a medical degree. As ever, drama and romantic chaos are never far from Nina's door. This season she must manage a whole new onslaught of mishaps and revelations, as well as unprecedented professional and personal trials that will see Nina, Billie and the Proudman clan tested as never before. When a tragedy brings the family back together, the stability of life unravels, forcing them once again to question what they thought they knew about themselves and the past - and changing the dynamics of the family forever.
