Ziggy, Mark Lester is an English boy who spends the summer in Malta with his adult sister, Pippa Susan George at their grandfather's lighthouse, Lionel Jeffries. To chase away boredom, he builds a vivid, immersive fantasy world of adventure that lifts his spirits and fills the days with small-scale heroics. Yet this imagination also earns him a reputation around the family as the world’s worst liar, a label that will be tested by what he sees and, more importantly, what he refuses to forget.
One day, Pippa drives Ziggy to town to join crowds greeting a visiting African dignitary. They blend into the festive bustle as Ziggy follows the shifting light of the celebrations and searches for a better view, while a young tourist named Tom Tony Bonner becomes a new face in the mix. The mood of celebration shatters in an instant when the dignitary’s open-top car is fired upon and the occupants are slain. Ziggy is the lone spectator who truly witnesses the assassins, one of whom wears a police uniform. Realizing the boy has seen them, the attackers surge after him through the town, but Ziggy darts away and escapes their grasp.
As the danger closes in, Pippa and Tom locate Ziggy at the town’s edge. Back at the lighthouse, Ziggy begins to recount what he saw, but neither his sister nor Tom fully believes the breadth of his tale. Later, a Malta TV broadcast announces martial law and a curfew, forcing Tom to spend the night with Ziggy, Pippa, and Grandfather as the island’s mood darkens and the night deepens.
The tension sharpens when Grandfather and the others start to sense that Ziggy’s story might be true. Police officers begin to appear at the lighthouse to check who is staying there, sending Ziggy into a panic and sending him fleeing once more. He finds shelter with Ann-Marie Maxine Kalli, a young friend who has been drawn into the dangerous atmosphere. In an act of help that quickly spirals, she breaks curfew and is picked up by the authorities. Her fate soon reveals itself: she is slain by the assassin’s brother, a renegade cop, turning Ziggy’s warning into a personal tragedy that underscores the stakes of what he witnessed.
The danger intensifies as the killers close in, pursuing Ziggy into the catacombs beneath a church. They kill a priest who has offered sanctuary to the boy, but Ziggy miraculously escapes once again, his nerves steelier and his resolve hardened by fear. The pursuit threads back toward the lighthouse, and the family splits their efforts to locate Ziggy before the night fully closes in on them.
When they finally reach town, Pippa, Tom, and Grandfather locate Ziggy hiding under a table in the dead priest’s church. The moment is fraught with relief and renewed urgency as the uniformed assassin spots their car and opens fire on the house itself. In a desperate bid to hold the attackers at bay, Grandpa and Tom improvise Molotov cocktails using paraffin lamps filled with brandy, creating a volatile defense that buys precious time for the boy and his relatives to slip away toward safety in Pippa’s vehicle.
What follows is a tense, late-night chase along the winding roads toward Malta’s rugged coastline. The pursuit culminates in a dramatic clash beside the cliffs: the assassin rams Pippa’s car off the road, sending it rolling toward the edge. As the vehicle teeters on the brink, Grandpa and the Chief of Police arrive just in time to shoot the assailant, whose cruiser plummets over the cliff and into the water below. In the quiet that follows, Ziggy’s earlier account, once dismissed, lingers in the air as a stark reminder of how a single boy’s truth can unravel a dangerous conspiracy and save lives when courage finally meets the moment of truth.
