Sally Hawkins and Eddie Marsan star in director Mike Leigh's seriocomedy concerning an eternally optimistic teacher living and working in North London. Thirty-year-old teacher Poppy (Hawkins) always has a smile on her face, and does her best to brighten the days of those around her by making small talk and cracking jokes. For the past ten years, Poppy has lived with her best friend, Zoe (Alexis Zegerman), a fellow teacher whose wry outlook on life serves as the perfect counterbalance to Poppy's effervescent charm. One day, Poppy decides that it's time to take driving lessons and enrolls in the Axle School of Motoring. Almost instantly, Poppy and her stressed-out instructor, Scott (Eddie Marsan), clash. Still, it seems that there's more to this relationship than surface appearances would suggest. After accompanying her colleague Heather (Sylvestra Le Touzel) to a tango class taught by a particularly passionate instructor (Karina Fernandaz), Poppy connects with kindly school social worker Tim (Samuel Roukin). Of course, Tim can't help but fall for a woman of such boundless compassion, but how will Poppy's increasingly jealous driving instructor react to the news of her most recent romance?
