The trailer features the duo taking a family ski trip with their two kids when disaster strikes and an avalanche engulfs their resort.
The family is safe but Louis-Dreyfus becomes upset with how Ferrell ran away during the avalanche and left his family behind.
Ferrell claims that he left to go get help and that it would be impossible for him to run away in ski boots.
The couple must then reevaluate their marriage and their feelings for each other.
Downhill, from directors Nat Faxon and Jim Rash, is set to arrive in theaters on Feb. 14.
