'Can you still see yourself sitting on a park bench, holding hands with that person when they are old and wrinkly? That's the question you have to ask yourself.' Aspiring journalist Becky loves her boyfriend Alex, but when her best friend Katie gets engaged, she's left wondering if Alex really is her Mr Right. Their other best friend Emma doesn't believe in 'the One'- she's just looking for a man who will stick around longer than her dad did. As they come together to plan Katie's big day, navigating the chaos of wedding dress shopping, seating plans, and the dreaded singles table, the girls begin to question their own relationships; and the possibility of settling for anything less than butterflies.
