Warner Bros. Pictures has picked up the action spec "The Ditch" from music video and documentary producer Sascha Penn says Variety.

Set in the future, a super maximum-security prison has been constructed on one of Jupiter's moons where Earth's worst criminals are incarcerated.

When a prison guard's family is taken hostage, he is coerced into helping the facility's most notorious terrorist, a man who was scheduled to be executed that day, escape.
