The Imposter (2025 TV Series) Synopsis
The Imposter is a 2025 TV series that follows a family drama set around a seaside hotel where long-buried secrets resurface with deadly consequences. Helen, a fiercely independent matriarch, refuses to sell the family’s beachfront property despite mounting pressure from her adult children, each of whom sees the hotel as a financial escape. Tensions escalate when Amanda arrives, claiming to be the daughter Helen gave up for adoption decades earlier, reopening emotional wounds and unresolved guilt.
As Amanda integrates herself into the family, doubts begin to form about her true identity and intentions. The hotel becomes a pressure cooker of suspicion, jealousy, and betrayal, with past decisions colliding violently with the present. Flashbacks slowly reveal what really happened years ago, while lies in the present spiral out of control. What begins as a dispute over property transforms into a psychological thriller, where deception, manipulation, and greed ultimately lead to murder.
