Season 20 kicks off with a magician who recruits home viewers to participate, a danger act with a superhuman ability and Golden Buzzers that captivate the judges. Simon, Mel B, Sofia, Howie and Terry invite cameras behind the scenes.

Howie jokes that a group of clown magicians nearly gives him a heart attack. Siblings test their bonds and talent on the audition stage. Sofia and Mel battle it out to be the first to hit the button over a jaw-dropping Golden Buzzer.

The judges are shocked by how many Season 20 auditions bring new firsts to the AGT stage. From an aerialist duo flying under a water rig to the first robot-dog boy band, week three makes show history.

A powerful magician takes control of the theater and Howie's personal phone. One act receives a surprise Golden Buzzer for a talent 45 years in the making.

A Kentucky truck driver is far from home as he braves the AGT stage. A roller-skating aerial act from Simon's past tries to earn his respect and "Vanderpump Rules" star Tom Sandoval auditions.
