A Bump Along the Way tells the story of fun-loving, 44-year-old single mum Pamela (Bronagh Gallagher) who becomes pregnant following a boozy one night-stand with a man half her age, much to the shame of her buttoned-up teenage daughter Allegra (Lola Petticrew). As Pamela deals with her unexpected pregnancy and the growing pains of the disgruntled Allegra, the challenges they both face ultimately bring mother and daughter to a better understanding of themselves and each other.
