'ER' veteran Sherry Stringfield will co-star opposite Virginia Madsen in TNT's 'Hornet's Nest.'

Based on the Patricia Cornwell novel, the film will be part of TNT's Mystery Movie Night and debut spring 2012. Madsen will play police chief Judy Hammer and Stringfield will play her top deputy, Virigina West. The two make a serial killer their top priority.

Robbie Amell plays reporter Andy Brazil, Michael Boatman co-stars as Richard Panesa and Michael Silver rounds out the cast as Hammer's deputy chief, Adam Goode. Hammer pairs Stringfield's character up with Brazil's cub reporter, causing some friction.
