The film tells the story of John Bennett (played by Mark Wahlberg), a 30-year-old man who wishes upon a star that his teddy bear, Ted (voiced by Seth MacFarlane), comes to life. To his surprise, Ted becomes a living, breathing, foul-mouthed entity. The two were inseparable as children, but as John grows older, Ted's existence becomes a source of embarrassment and conflict. When John meets the love of his life, Samantha (played by Mila Kunis), Ted's presence sparks tension in their relationship.
