Marriage Retreat (2011)

When a group of best friends decide to go on a marriage retreat in the mountains for no deeper reasons to relax and have a little fun, they discover the true states of their marriages and how far apart they have drifted. Once there, Dr. Sullivan (Fahey) and his wife Katrina (Jackson) challenges them to confront their own sins to heal their relationship issues through some rather unconventional methods grounded in Biblical principles.
