A rehash of Mel Gibson's "Ransom" with younger, prettier parents fighting back against their child's kidnappers, the film stars the luscious Charlize Theron ( "Sweet November" ) and darkly charming Stuart Townsend ( "Queen of the Damned" ) as a rich, happy young couple with a lakefront, Architectural Digest home but without much credibility as parents to a pretty 6-year-old daughter (Dakota Fanning, "I Am Sam" ).
