Rebel Wilson plays Natalie, working as an architect in New York City, though often marginalized by her peers at her firm as one of the administrative assistants who make copies and fetch coffee for the others a the board meetings. To make matters worse, she ends up getting mugged and assaulted in the subway, resulting in a loss of consciousness that finds her waking up in a too-nice hospital being catered to, and flirted with, by the handsome doctor there. Her apartment is now three times the size and meticulously furnished, her neighbor now flamboyantly gay, and the hunky, wealthy client they’ve recently taken on at the firm (Liam Hemsworth) now only has eyes for her. In short, she’s the star of her own romantic comedy, and the only person she can confide in that knowledge is her best friend at work, Josh (Adam Devine), who holds a secret crush for Natalie that she’s been too stuck in her low self esteem to see.
Hiccup is now into adulthood, young but now the leader among the Dragon-rescuing Vikings of their island fortress village of Berk. Though the Vikings have lived in Berk for generations, Hiccup soon sees that they’ve outgrown their small island, especially with the overcrowding of the Dragons there as they rescue more of them, eyeing the mythical sanctuary on the edge of the world to guide these magical beasts. Meanwhile, love may be in the air, with Hiccup perhaps on the verge of marriage with Astrid, though she seems reticent, and Toothless perhaps finding a mate with a female Dragon very much like him, dubbed a “Light Fury” due to its alabaster color, in contrast to Toothless’ obsidian appearance. Unfortunately, it’s all a trap set by Grimmel, the notorious hunter of Night Fury dragons, who aims to snuff them all out at any cost.
