Don't Tell a Soul (2020)

To support their dying mother Carol, 17-year-old Matt forces his 14-year-old brother Joey to rob a remote home being fumigated. Security guard Dave Hamby chases the two boys through a forest, but falls into an abandoned well. Matt insists on leaving Hamby in the hole so he cannot turn the brothers in to the police.

Feeling guilty about leaving the man trapped, Joey regularly visits Hamby to bring him water, food, a sleeping bag, and a walkie-talkie. When he discovers what his brother is doing, Matt urinates on Hamby's head to reassert authority. Incensed when Joey continues bonding with the man, Matt drops an open pesticide canister into the hole to kill Hamby. Joey confronts Matt when he learns his brother used the stolen money meant for their mother to host a motel party. Matt responds by telling partygoers that Joey steals from retired people. Joey retaliates by revealing that Matt killed a man. Matt threatens and beats Joey. Joey runs back home where Carol's TV news program reveals the man in the well is actually Randy Michael Sadler, a fugitive wanted for murdering his wife and children. Joey returns to the hole and discovers Randy survived the pesticide by wearing the gas mask Joey dropped during the chase. Randy admits he stole a security guard's uniform and was trying to retrieve the stolen money for himself. Joey bargains to rescue Randy from the well in exchange for help punishing Matt. Joey brings Randy home after using a rope to get him out of the hole. Carol recognizes Randy from the news bulletin. Carol is shocked to discover Joey is helping Randy go on the run. At the same time, Matt reports Joey as the thief to police officers Smith and Crane, who are investigating the initial vandalism; Matt inadvertently implicates himself in the robbery (and knowing Randy was imprisoned in a hole but failed to notify police). Matt accompanies the two officers back to the house where a standoff ensues with Randy. Randy shoots both officers, but Joey stops him from killing them. Randy and Joey then take Matt to the hole in the forest. After forcing Matt into the well, Randy compels Joey to shout angry invectives at his brother. Randy then pushes Joey into the hole. Matt beats Joey unconscious. Randy starts limping away when Carol confronts him at gunpoint. Carol reveals she killed her abusive husband. Following a conversation about her troubled family, Carol shoots Randy dead. Fearing he killed his brother, Matt finally manages to rouse Joey. Matt and Joey embrace as Carol comes to their rescue.
