Michelle Monaghan Plays Twins With a Dark Secret in Echoes Trailer

Netflix has released the new trailer for Echoes, a mystery thriller starring Michelle Monaghan as identical twins, Leni and Gina, "who share a dangerous secret."

Leni and Gina have secretly swapped lives since they were children, and now, as adults, they both live double lives. They share two homes, two husbands, and a child, but when one of the sisters suddenly goes missing, their perfectly choreographed world is thrown into disarray.

The Echoes trailer includes a series of clues about what happened to Leni, leaving viewers to wonder whether she was taken or killed, or simply ran away.

The seven-episode limited series also stars Matt Bomer, Daniel Sunjata, and Ali Stroker, among others.

Echoes premieres August 19 on Netflix.
