CNN Heroes: An All-Star Tribute is set to kick off this year's hero with two presentations hosted by Anderson Cooper, Stars and Stripes Unite and Rescuing the Rivers, the network announced today.

Anderson Cooper goes behind the scenes with Kid Rock, Gary Sinise and Kathy Griffin, as they discuss their personal support and journeys with the troops, through sit-downs and performances, in Stars and Stripes Unite. The special airs Nov. 7 at 10 p.m.

Last year's Hero of the Year, Chad Pregracke, will be honored in Rescuing the Rivers on Dec. 5 at 10 p.m., as he explains his cleanup operation along the Mississippi River and American waterways. Pregracke's efforts have removed eight million pounds of garbage over the past 17 years, earning him the 2013 Hero title.

The event will finish with CNN Heroes: An All-Star Tribute on Dec. 7 at 8 p.m., which will recognize individuals making tremendous efforts to help others.
