Bossy Bride features Jesse and Emma getting almost-hitched on a roller coaster, tricked into being the stars of a pirate show, jumping out of an airplane, and saying their vows in front of two huge Italian families who don’t speak English. It’s a rompy, whirlwind trip down a rabbit hole of “Fantasy” Vegas weddings planned by a man called “Fingers” and just when you think nothing else could go wrong—a mermaid descends from the ceiling.
