Suddenly

Baron leads four assassins who impersonate Secret Service agents, targeting Ellen's house in Suddenly as the staging ground for the presidential assassination. They intend to use the house during the president's visit to kill him with a sniper rifle. The plan relies on fooling local authorities and maintaining secrecy until the moment of attack.

The assassins' cover works against the town's police, who are deceived by the imposter agents. Deputy Todd Shaw, a washed-up war hero and town drunk, senses something is off about the intrusion. His suspicions are ignored by the authorities, delaying any warning.

During the tense infiltrations, Ellen's father suffers a heart attack and dies. The death is attributed to the stress and fear caused by the impostors. Ellen's family is plunged into tragedy as the threat looms closer to home.

Ellen's teenage son Pidge finds an opportunity to slip out and seek help. His escape alarms the intruders and sets a chain of events in motion outside the house. The attempt to summon aid becomes the first cracks in the attackers' plan.

Todd arrives to monitor the situation and becomes convinced something is seriously wrong. Despite skepticism from others, he fights one of Baron's crew and kills him before being captured. This marks Todd's initial act of defiance against the conspirators.

Two assassins talk with Todd and Ellen while waiting to execute the plan, revealing a past connection: Todd accidentally killed Ellen's husband in Iraq during a grenade attack on a moonless night. The confession adds personal tragedy and guilt to the ongoing crisis. Ellen's trust in Todd deepens, but danger remains.

The third assassin catches Pidge as he flags down local electrician Judd, dragging them back toward the house. Judd becomes reluctantly involved, complicating rescue efforts. The dynamic inside the house grows more chaotic as bystanders become entangled.

Judd tricks the assassin into turning on a switch for the lights, delivering a fatal electric shock. The assassin dies, reducing the immediate threat to Ellen's household. Baron tightens his control over the remaining accomplice and the operation accelerates toward its conclusion.

Baron kills his remaining partner who expresses doubts about the mission. The group is left with a single assassin as pressure builds to carry out the shooting. The internal collapse foreshadows an unstable finale.

Baron fires at the President, but the shot only grazes the President's arm. The assassination attempt nearly succeeds but fails due to a momentary misstep. The tension peaks as Todd prepares to intervene.

As chaos continues, Pidge shoots Baron just as he is about to kill Todd, ending the main threat. The President's life is saved, though the events leave a mark on the town. Ellen and Todd confront the aftermath and relief mixed with trauma.

Todd uncovers evidence of an unknown fifth conspirator communicating with Baron through text messages. The discovery undermines the idea of a wider conspiracy and points to a tightly contained plot. The revelation reframes the threat as localized rather than orchestrated by unseen networks.

Todd becomes the town's reluctant hero as the President's life is saved. The media touts his actions and his role in stopping the attack, but the official narrative insists Baron and his men acted alone. The suggested absence of a broader conspiracy leaves the town to process the event.
