In the irreverent spirit of fun that made “The Lego Movie” a worldwide phenomenon, the self-described leading man of that ensemble—Lego Batman—stars in his own big-screen adventure. But there are big changes brewing in Gotham, and if he wants to save the city from The Joker’s hostile takeover, Batman may have to drop the lone vigilante thing, try to work with others and maybe, just maybe, learn to lighten up.

Sean Reynolds, a highly acclaimed investigative journalist (who strongly believed in paranormal phenomena), destroyed his career when the most watched episode of his reality show, based on paranormal phenomena, turned out to be a hoax. Sean saw a news report on a “Bigfoot Hunter” (Carl Drybeck) who claimed to possess the body of a dead Sasquatch. He believes Drybeck is a phony and decides to create a new show that reveals people’s paranormal claims as hoaxes. Sean assembles his old film crew and heads to Northern California’s “Lost Coast” to meet with and interview Drybeck. Obsessed, Sean is staking his comeback, his life and the lives of his documentary film crew on proving Drybeck’s claim to be a hoax.
