The specific plot for the movie hasn’t been revealed yet, but we can expect the basic premise from the comic books to be the same. The Suicide Squad, officially designated Task Force X, is a secret team of supervillains that have been imprisoned by the United States government. The team undertakes high-risk missions for the government in exchange for amnesty. If they succeed in their mission, they live to fight another day and get their sentences reduced, but if they fail, the government can just write them off. Hence the nickname "Suicide Squad." Team members also have micro bombs implanted inside them, which can be detonated if they try to escape or cause trouble during the mission. It has not yet been revealed what mission the team will be going on in the movie, but that information should come with time.
