Just watched a movie with a horrid story line, I hope it's NOT basics on a true story!! It's about a heavily pregnant woman wakes up in some place in a ice bath. Those who put her there must of drugged her and give her a c section and took her baby while out of it. She has no clue, later finds 3 women same thing for them &another one creeping round killing the others to get a colored plastic tab hidden in there stomachs coded to what baby is theirs. They later find the baby's locked in Metal cages, the people responsible is sat in a hidden room watching everything on these tv screens At the end the last one standing has to watch her baby given away to a couple while she's chained up with a gun to her head. my heart sank now I feel sick after watching it, i love a gd horror movie but sometimes I wonder how do people come up with such twisted movie plots.
