“Frozen” is this week’s film at the Southampton Chamber of Commerce’s Coopers Beach Drive-In.

Fearless optimist Anna sets off on an epic journey-teaming up with rugged mountain man Kristoff and his loyal reindeer Sven-to find her sister Elsa, whose icy powers have trapped the kingdom of Arendelle in eternal winter. Encountering Everest-like conditions, mystical trolls and a hilarious snowman named Olaf, Anna and Kristoff battle the elements in a race to save the kingdom.

This is the fourth of a series of four Monday night drive-in movies at Coopers Beach. Gates open at 7 p.m., movie starts at dusk. FM car radio needed for movie viewing. No beach pass needed.
