Lionsgate dropped the first details for John Wick Chapter 3 at CinemaCon. The synopsis, which is more a summary of the end of Chapter 2, tells that John Wick will now be fighting his way out of New York City with a $14 million bounty on his head and without any of the Continental's help. He'll use what the synopsis refers to as the "service industry" to help make his violent escape.
They've also released a very boring promotional poster, which you can view below.
