The Host Movie Wiki

Melanie "Mel" Stryder is one of the surviving rebel humans left after humans became extinct from the 'souls', parasitic aliens which take over human bodies, erasing the original occupants. Mel goes on raids to find food for her younger brother Jamie. Another human Jared Howe finds her and chases her as he does not want to be alone and kisses her unexpectedly. Wanderer is a Soul who has lived on eight other planets previously, Mel being her ninth body host. Melanie had thrown herself down an elevator shaft to prevent herself from becoming a host, while being chased by Seekers. Wanderer was inserted into Mel's body under emergency conditions after Melanie survived, with the intent of using her to access any information Melanie might have about other free humans like Mel's brother and boyfriend. This investigation is headed by an individual identified only as "The Seeker", who pressures Wanderer to produce information, and views her with implied contempt for her failure to do so. The Seeker pressure her into to going to Tucson to be removed from Melanie's body as it seemed that Wanderer couldn't access Melanie's memories.
