Countdown

The plot follows a group of people who discover a mobile app that correctly tells its users when they are going to die.

Countdown was theatrically released in the United States on October 25, 2019, by STX Entertainment. It received negative reviews from critics but grossed $48 million worldwide against a $6.5 million budget, becoming a commercial success.

After avoiding getting into a car with her drunk boyfriend Evan, Courtney receives a notification stating she has broken the “user agreement”. Returning home, she is attacked by an unseen entity and killed as her timer reaches zero. At the same time, Evan crashes his car and a tree branch impales the seat where Courtney would have been sitting.

Quinn Harris, a nurse who works at the hospital where Evan is admitted, dismisses his claims of a supernatural app but subsequently downloads it only for it to claim that she has only two days left to live. Evan skips his surgery and is informed he has violated the user agreement. He tries escaping the hospital but is confronted by an apparition of Courtney in a stairwell before being killed by the entity.

When Quinn finds out that Evan has died, she enters the morgue and checks his phone, which indicates no time left in the app. Concerned that she will die the next day, Quinn declines to go out with her family to visit her mother’s grave. The app informs her that she has violated the user agreement. Shortly afterward, her boss Dr. Sullivan sexually harasses her and thwarts her attempt to report his offense to her supervisor. When Quinn researches the app, she finds that similar deaths have supposedly occurred involving other users, but the public generally considers them to be fake. She attempts to buy a new phone but finds that Countdown has downloaded itself onto it.

After being attacked by a demonic figure in the parking lot of the cell phone store, Quinn meets a young man named Matt, whose Countdown states he will die in 18 hours. They learn that the user agreement is broken if the user tries changing their fate: Quinn’s trip with her family, and Matt taking a train ride, which they both canceled, should have resulted in their original deaths. At work, Quinn learns Sullivan has tricked the staff into thinking she sexually harassed him, resulting in her suspension. She and Matt consult a priest named Father John, who informs them that the app is linked to a demon named Ozhin, originally summoned by a Roma woman who told a prince when he would die. Cell phone salesman Derek hacks into the app code and identifies that Quinn’s younger sister, Jordan, was meant to die shortly before Quinn, then adds several decades to Quinn, Jordan’s, and Matt’s lives. However, while Matt and Quinn spend the night together, the entity takes the form of Matt and attacks Quinn. To their shock, their countdowns, including Jordan’s, reset to their original lifespans.

Jordan receives a notification of her countdown changing to the original lifespan and is then terrorized by a demonic form of her and Quinn’s deceased mother. Quinn and Matt rescue her and return to Father John, who theorizes the curse can be broken if someone dies before their countdown ends or lives beyond their countdown. They prepare a warding circle in an attempt to delay Ozhin. The demon arrives and the circle initially wards off the demon, until it suddenly lures them outside, killing Matt and wounding Jordan in the process. While in grief over Matt’s fate, Jordan starts having serious abdominal pain. Realizing her sister is seriously hurt, Quinn rushes Jordan to the hospital. Once there, she realizes she can kill Sullivan before his allotted time and end the curse. She attempts to attack him, but he is saved by Ozhin, who simultaneously prepares to kill Jordan as Ozhin is terrorizing Jordan, Quinn overdoses on drugs before her timer ends and proves the app wrong. With instructions that Quinn gave her, Jordan revives her sister with Naloxone and their countdown timers stop. Sometime later, while visiting her and Jordan’s mother’s grave, Quinn receives word of Sullivan’s arrest after more nurses have come forward, but discovers that an app called Countdown 2.0 has downloaded itself onto her phone, much to the sisters’ horror.

In a mid credits, Derek is seen on a Tinder date, while his date goes to the restroom, his Countdown app causes the light to go out. As the screen cuts to black, Derek’s screams are heard as Ozhin attacks him.
