Heartburn is a modern take on the rom-com that looks at fatness and friendship. Set over one night in Belfast it follows Chris, a writer, and Lou, a “dinner-lady man” by day and pint puller at night. The two met at university and quickly became friends with benefits. Chris moved back to Belfast, and now, two years later, Lou turns up on her doorstep on New Years Eve with a bottle of prosecco and some questions that need to be answered. Over the night the two reminisce, drink, laugh, eat and try to reckon with their relationship. Can they be mates, should they get together, or should they just call it a day?
