There are four kinds of alien encounters.  The fourth kind is abduction.

The Fourth Kind: Deleted Scene

In remote Alaska, citizens have been mysteriously vanishing since the 1960s. Despite multiple FBI investigations, the truth behind the phenomena had never been discovered - until now.  While videotaping therapy sessions with traumatized patients, psychologist Dr. Abigail Tyler (Milla Jovovich) unwittingly exposes terrifying revelations of multiple victims whose claims of being visited by alien figures all share disturbingly identical details.  Based on actual case studies, The Fourth Kind uses Dr. Tyler's never-before-seen archival footage alongside dramatic reenactments to present the most disturbing evidence ever documented in this provocative thriller critics are calling "terrifyingly real...The most shocking alien abduction movie to date."
