A huge plot detail about the upcoming 'Captain America: Civil War' film has been revealed by Heroic Hollywood.

Their report insists that the international incident that sets up the events for the Civil War to be caused in a scuffle with Captain America and Scarlet Witch vs. Crossbones.

"The rumor is, according to trusted sources, the international incident in the film involving the Avengers that results in collateral damage involves Captain America and Scarlet Witch who are trying to apprehend Crossbones. The only problem is that Crossbones is wearing a suicide vest full of nasty explosives. In order to protect the civilians on the ground, Captain America orders Scarlet Witch to levitate Crossbones above ground. She does and unfortunately is unable to contain the massive explosion that sets off near a populated building causing death and destruction," writes Heroic Hollywood.

This event appears to be closely similar to the event that set the story off in the comics. The movie will be loosely adapting this storyline, but will adhere to the Superhero Registration Act that divides Captain America and Iron Man into opposing sides.

What the Registration Act plans to do is get every super-powered being to reveal their identity, while also adhering to the rules and regulations of S.H.I.E.L.D.. Each character is seen joining a certain side for their own personal reasons, which then results in a superhero battle of epic proportions.

This event is also believed to have been referenced in an easter egg in 'Ant-Man.'

"In a scene from Ant-Man, a passenger on a passenger on the San Fran trolley is reading a newspaper with the headline, "Who's To Blame For Sokovia?" It's a reference to Avengers: Age Of Ultron and the set-up for both the end credits scene, and Captain America: Civil War," writes Heroic Hollywood.

'Captain America: Civil War' drops into theaters on May 6, 2016.
