Free Guy tells the story of Guy (Ryan Reynolds), an NPC in an MMO video game called Free City who unexpectedly gains sentience and uses it to achieve his true potential. Aided by video game developer Keys (Joe Keery) and player character Millie (Jodie Comer), Guy helps to uncover Free City's source code in an attempt to prove that its developer (Taika Waititi) stole the code. With his best friend, NPC Buddy (Lil Rel Howery) at his side and armed with an array of video game weapons, Guy must face threats from both inside and outside of his virtual world.
