You know what you're in for when you head along to an action comedy staring Dwayne "The Rock" Johnson as a CIA agent and Kevin Hart as his reluctant sidekick - a slice of silly, light-hearted escapism.
What you may not expect is The Rock manages to steal scenes from his comedian co-star.
Johnson plays Bob Stone, who as a teenager was overweight and bullied. But Bob has the last laugh when he returns to his hometown to attend his high school reunion - he's now a CIA agent and ripped.
He organises a catch-up with Calvin Joyner (Hart), who was voted at high school the most likely to succeed and is now, well, a disillusioned accountant, and the two get on well, until it becomes apparent Bob is in a spot of trouble at work and has gone rogue, and Calvin and his forensic accounting skills are required to join him on the run to help clear his name.
