Supapat Phoncharoenrat

It's Back to the Future for a young Thai guy who discovers a message on an old pager and is transported 20 years back in time to 1995, altering the events in which his parents met and fell in love.

Daya was studying abroad when her father died under obscure circumstances, so she hastily has to return home to Thailand. She tries to solve the mystery of her father's death with the help of Taywat, the son of the family's lawyer. They get closer to each other and their relationship eventually turns into love.

In this fantasy investigation series, investigators from two eras must hunt for the truth in old unsolved cases, communicating only through an old radio. The signal between the past and the present only opens at 23:23.
