Islands

Dave disappeared after discovering he was infertile and suspected he might not be the father of his son Anton. That night, he called Anne threatening to jump from a cliff unless she told him the truth about Anton's paternity. He then wandered onto the beach and eventually attempted to reach a nearby volcano, where he was found naked and delirious.

Earlier at dinner, tensions about the timing of their marriage and the challenge of having another child hinted at underlying marital strain.

Dave was found alive the next day, naked and delirious, after attempting to reach a nearby volcano. He was hospitalized and reunited with his family. He had apparently survived in a disoriented state somewhere on the island after his emotional breakdown.

The surfers mentioned Dave's erratic mood and cruel things he said about his wife, indicating he was in a fragile mental state.

Anne deleted the record of Dave's threatening call because she wanted to hide what he had discovered, his infertility diagnosis and his suspicion that he might not be Anton's biological father. The call contained his demand for the truth and his threat to jump from a cliff.

The deleted record was first noticed by Inspector Mazo, creating immediate suspicion around Anne's motives.

Dave had been diagnosed with infertility, which led him to doubt whether he was the father of his young son Anton. This revelation caused a massive emotional crisis, triggering his disappearance after confronting Anne about the truth.

During dinner, Anne and Dave discussed their rushed marriage and the difficulty of having another child, hinting at fertility struggles.

Tom lied to Inspector Mazo about Anne's whereabouts twice, first claiming she left the hotel to see him, then again when Mazo mentioned having an incriminating witness. Tom was developing feelings for Anne and wanted to protect her from further suspicion, despite knowing she was hiding something.

Tom's growing attraction to Anne was evident during the island tour and their night out at The Waikīkī, where tensions between the couples surfaced.

The film doesn't explicitly reveal whether Dave was Anton's biological father. Dave suspected he might not be due to his infertility, which drove his emotional breakdown and threat to jump from a cliff. Anne never definitively confirmed or denied the truth during the film.

Dave's infertility diagnosis and his specific accusation that Anne was hiding something about Anton's paternity set up this central mystery.

Anne's seemingly carefree behavior, drinking martinis, topless swimming, and shopping, during Dave's disappearance investigation came across as suspicious and insensitive. This could be interpreted as either a coping mechanism for the stressful situation or deliberate bravado to mask her guilt about the deleted phone record and her infidelity with Tom.

Tom himself grows unsettled by Anne's casual demeanor, describing her as exhibiting 'casual bravado' while the police investigation intensifies.

At the end of Islands, Tom drives to the airport in a moment of impulse and buys a plane ticket, but the film lingers on his face as he hesitates about where to go next. It's ambiguous whether he actually leaves or stays, representing his ongoing struggle with aimlessness and the question of what, if anything, calls him beyond the island.

The film opens with Tom's monotonous routine, days of tennis lessons and nights of partying, establishing his unanchored existence that the ending revisits.

Tom and Anne give in to their mutual attraction and spend a night together during the investigation. This occurs after Mazo hints at having an incriminating witness, and Tom lies again to protect Anne's whereabouts. The encounter represents a fragile moment of connection that lingers above the truth they both fear.

Anne's increasing frustration with Dave and her pull toward Tom was evident during the island tour to the lava caves and beaches, where she appeared increasingly drawn to him.

Inspector Mazo travels from Lanzarote to head the investigation into Dave's disappearance. He is hard-nosed and quickly suspects foul play. He reveals that Anne deleted a phone call record, questions Tom repeatedly, and hints at having an incriminating witness, though this witness never substantially materializes in the narrative.

Mazo's arrival marks a turning point in the investigation, shifting from Jorge's initial infidelity theory to deeper suspicions.
