The movie has an eerie feel to it throughout the beginning as Foster's character, Kyle Pratt, imagines her husband walking with her through the streets of Berlin; you don't realize Kyle is actually alone until she reaches home.

The movie focuses on Kyle and her daughter Julia (newcomer Marlene Lawston) traveling to the United States to bury her husband, who has died in a freak accident. The family lived in Berlin, where Kyle is an engineer -- an engineer who just happened to design the engines on the aircraft Kyle is using to get to the United States. Coincidence? Of course!

Once the mother-daughter duo boards the plan, Kyle assures her daughter that she will like America, and suggests the two move to the back of the plane and sleep in the empty rows.

The idea of the majority of a 90-minute movie that takes place on an aircraft brings about a sense of claustrophobia.

However, this plane is unlike any other; it seats more than 400 passengers on two levels and has a crew of roughly 12.

This gives characters more places to roam while on board and a chance to grab a drink in the plane's lounge.

Three hours into the transatlantic flight, Kyle wakes up to find her daughter missing from her row. Kyle, immediately filled with adrenaline, goes running back to her original row to find her daughter not there either.

She quickly questions the other passengers around to see if they had seen her daughter, and all passengers answer with, "I didn't know you had a daughter with you."

Not only does this play into the fact that she imagined her husband hours before the plane ride, but maybe she is imagining her daughter as well. Kyle, who is very familiar with the plane's ins and outs, quickly asks the flight crew to check the plane.

Throughout the interrogation of Captain Rich (Sean Bean), flight attendant Stephanie (Kate Beahan) double checks the flight list and realizes that Kyle came aboard alone and that her daughter is not registered. This sends Kyle into an absolute fury that sends panic and doubt through the flight's passengers.

Finally, air marshal Carson, played by Peter Sarsgaard, comes to Kyle's rescue and assures her that all will be fine.

Sarsgaard, who played the tag-along friend in Garden State, does an incredible job of playing the air marshal who starts off as Kyle's friend and slowly turns on her.

After the crew searches for Kyle's daughter and comes up empty handed, one might conclude that she did, in fact, imagine her daughter on the flight with her, and you start to actually feel for her. Foster plays Kyle brilliantly, the way only a real mother could.

She forges on and does whatever she can to find her daughter, even if that means breaking into the electrical box on the plane and deploying the air masks.

Not to spoil anything for those who are fans of either Sarsgaard or Foster, but the ending is a happy one filled with answers. Even answers as to why the death of Kyle's husband is so suspicious.

This is one plane ride that should not be missed.
