247°F (2012)

A pleasant schvitz turns into a hell trip fo a group of friends caught in the titular killer sauna of 247°F (2011). Four friends, played by Scout Taylor Compton, Travis Van Winkle, Michael Copon, and Christina Ulloa, are spending the weekend at a relative's cabin (as kids in horror movies are prone to do), but the fun time turns into an endurance trial when they are accidentally locked inside a hot sauna on the property. Yup, that's it. Oh-- and Scout and Christina are in their skivvies the entire time. That'll make you shake your thermometer!
