No Spoilers Here: Character Introductions
1. The Owners begins slow & painful, like inching a bandaid off a large wound. Three young adult (yeah, we'll call them that) males sit in a small red (significant) car, awaiting for the right time to exact [what we shortly find out is] a robbery. Getting the loot should be simple enough, given the homeowners' elderly state (and the fact that the job was to occur during the occupants' absence). The color of the car isn't pointed out as a factor in the movie events; however, I can only imagine that, in a sea of countryside greenery, a huge spot of red might be a dead (no pun) giveaway.
2. Turns out, the get-away vehicle is borrowed, from the master-mind's "girlfriend". The girlfriend rolls up on a bike, because, she needs her car to get to work. NOTE: Please check the owners' schedule, first, to confirm that your crime schedule doesn't conflict with her daily routine. Apprise the owner, if you're using her vehicle to commit a crime. Now, she's late for work and life, and, inadvertently, aided and abetted a crime. Oh, announced "I'm pregnant" to the 'boyfriend', who, suddenly, is robbing "for you and the baby".
3. The loudest, most thuggish, degenerate, hammer wielding, box-cutter brandishing of the three guys is the first to die, ironically, from a blow to the head by a hammer.
4. The 'boyfriend' has a box cutter lodged in his abs, left there from his physical altercation with the now deceased bad boy, referenced in #3.
5. Retired homeowners: him, physician; her, a nurse
6. Young adult female, car owner: had a twin sister, Jane, who once dated one of the three males.
7. The mother of the guy (Jane's former boyfriend) works for the homeowners. He is the person who told the other two guys about the homeowners' valuables.
8. The prey becomes the preyer, and, come to find out, the preyers have been preying, for many years. They have a scrapbook of commemorative news clippings, to relive their experiences. They once had a daughter.
9. Some lived. Some didn't live.
