    Love Trapped

    Former Bachelor Clayton Echard’s casual one-night fling turned into a paternity nightmare. When the news broke about the scandal, no one believed Clayton at first. He was a reality TV star, and an unpopular one at that. Clayton found himself trying to prove the truth, while trapped in a web of lies, manipulation, and threats. He would soon discover he was not the only one. At its core, this is a story about who you believe and why. It’s an epic battle that would take a group of strangers, citizen sleuths from across the world, to crack the case and finally hold someone accountable. New episodes of Love Trapped are released every Thursday, starting February 26th, 2026.
