"Across the Hall" is a love triangle with no sharp edges. A guy is taking a bath when he gets a call from a frenzied friend. The friend believes that his girlfriend is cheating on him. Drunk and carrying firearms, the friend has followed his soon-to-be ex-girlfriend to a hotel room.
The guy on the telephone is cheating on his best friend and is in the hotel room.
“Across the Hall” fails where “The Shovel” succeeds, a thriller that loses it's suspense due to complicated plotting. Each character overacts and the climax is confusing, yet somehow predictable.
