The Oscar winner stated that the Leverage team will face off against a force that is manipulating them, forcing the team to try to stick together "as a family", according to TV Line.
"Perhaps that the team has come together as a family, that they all now trust each other," Hutton said when asked about the theme for season four of the TNT series. "But just at the moment that they finally kind of trust one another, confident that no one is going to bail or go AWOL, they find that they're being watched by a very powerful group or person that is wanting to control what the Leverage team does, for their own gain."
Hutton went on to offer a small teaser for the upcoming season of Leverage.
"Keep your eye out for the stolen potato!" he added.
The actor recently described the new season of the show as tense, stating that the scrutiny will cause conflict within the ranks of the Leverage team.
It was reported in April that Danny Glover will be guest-starring in an episode of Leverage, portraying a retired war hero who comes into possession of a piece of art.
The fourth season of Leverage premieres tonight at 9pm on TNT.
