Five friends returning from a marriage in Canada return home to the United States. Not far from the border, two customs officers stop them to check their identity. Suspicious, they take their time especially with Jalil, a man of Arab origin. The situation worsens when a customs officer finds a small bag of marijuana in the luggage.
