Meet Sara - a veterinarian so skilled she can spay a tortoise one-handed. She's successful, she's popular - there's just one chink in her armour - she's too scared to tell her parents she's gay. On the evening of her 40th birthday, Sara's friends give her an ultimatum: either she tells her parents when they come to visit in six weeks' time, or they will. To help Sara achieve this goal, they've saved up to buy a series of sessions with Toria, the eccentric and mildly-qualified lifestyle coach / therapist, and so the countdown begins.
Sara is about to turn 40, and life is not as she imagined it would be. Whether it's making urgent funeral arrangements for a dead cat, lying about her personal life to placate her anxious mother, or getting into trouble with a netball referee, Sara's life is reaching tipping point and something's got to give. Much to Sara's dismay, it seems her friends are arranging a 'surprise' birthday party, but what she doesn't know is that they're about to set her a dramatic ultimatum.
Sara embarks on her course of life coaching with the eccentric Toria, but a hypnosis session has some unfortunate consequences for Justine. Daniel is feeling undervalued at work, and a disagreement with Sara turns into a full-blown vendetta on the paintball battlefield. And Sara's offer to help a distressed woman in a custody battle for her dog, leads Sara to meet Dutch action hero Kip Schwitzendorf.
Sara's ex-girlfriend Sabine turns up unexpectedly, throwing Sara's life into disarray. Eve seems keen to take her relationship with Sara further but Sabine's intervention throws a spanner in the works. Jamie is having a masculinity crisis and Daniel offers to rectify this with his own unique brand of machismo.
A veterinary inspector calls at the surgery, forcing Sara to get help from an unlikely source. A Russian woman gives Sara an ultimatum to arouse her dog and Daniel spends some quality time with the ladies.
Sara and the gang go to Toria's spooky family home, for a practice exercise in which Sara must come out to Toria's parents. Toria is forced to face her own fears, and Jamie and Justine share an intimate moment.
It's time for Sara to come out to her parents. Toria issues her with a lucky charm to bring good fortune, but it seems Sara's luck may be about to run out. With a break-in at the surgery, a snake on the loose, and a confrontational policeman, will Sara be able to overcome all hurdles and finally be honest with her family?
