Plot
Set in County Kerry, Ireland, this road movie follows 12-year-old Mully, whose mother Rita has recently died of cancer, and Joy, a solicitor, and her newborn baby. At a charity event in a local pub in Rita's honour, Mully sees his father James has stolen the money collected, to pay off his debts. Mully grabs the cash, runs off, and, finding a stationary taxi with the driver's door open, jumps in and drives off. He is shocked to realise that there are passengers in the back seat: Joy, a middle-aged woman in a drunken stupor, and her newborn baby. When the baby starts crying, Joy is overwhelmed, but Mully is able to calm the child. Mully swaps the taxi for a car in a used car lot, and insists on driving.
Mully and Joy take the backroads to remain undetected as he is an underage and therefore unlicensed driver, and they could be stopped by the police. They quarrel at first but later bond.
The car runs out of fuel. As they walk to get more petrol, Mully proposes that they take turns asking and answering questions. When queried, he explains about the hospice money, and Joy shares her plans to give up the baby to her friend Mags and then fly to Lanzarote, as she has not bonded with the baby and does not know who the father is.
Calling James from the petrol station, Mully is convinced by his father to head for a ferry, which Joy initially rejects. However, when a police checkpoint goes wrong, she changes her mind about the ferry, swapping for another car.
While waiting for the ferry, Mully helps Joy learn how to breastfeed Robin (she thought up the name upon seeing a robin alight nearby), as he had observed with his infant sibling. She tells him that she and his mother were in the same year at school, Joy one of the brightest and Rita extremely beautiful.
Mully’s father catches up with them, and Mully convinces him to let Joy and Robin go with them in the car. When Joy haemorrhages, they go to a B&B so she can get cleaned up and rest. In the meantime, his father has thought up a lie, wanting Mully to lie to the locals at the pub, and say he stole the money then got robbed.
Joy calls up her childhood friend Mags, letting her know she had the baby one week early, her name is Robin and she has breastfed her. She then tells her about a repressed memory from her childhood. One day, she and her mother saw her father cheating; afterwards, Joy had gone into the sea. When she was caught by an undertow, she saw her mother hesitate to save her. Joy tells Mags she will be there soon.
The next morning, before leaving, Joy gives the hospice money back to Mully so he can return it. Hurt that she is leaving him and going through with giving away Robin, he lashes out, insulting her. In a daze and with an emotional crisis, she drops Robin off on Mags's doorstep, then drives on to Kerry airport in deep denial about her own nascent feelings.
Joy boards the Spain-bound plane but immediately has a change of heart. Insisting they let her off, she races back to find Mully. Locating him, he initially tells her off, but James appears, demanding the money. Joy tries to protect Mully from his father, but Mully races to the water, throwing the cash over his shoulder. His father retrieves the cash, while she fishes Mully out of the water.
The film ends with Mags calling Joy to pick up a distraught Robin; Joy then drives by the pub with Mully to return the stolen money and they continue to collect the baby.
