Aline with Valentín. Miroslava with Sergio. Two couples. Two different worlds. One only destiny. Reflected upon one another, their lives intertwine in everyday's story. A story full of conflict and passion, triumph and failure. Thus, their lives get chained in beginnings and endings. For them, there's a lot to choose, a lot to start and a lot to finish. Thus, Aline and Miroslava punctuate their life with a period, and a new paragraph.

Set ten years after the finale's quintuple wedding, the special portrays the happily reunited San Román family, including four new grandchildren, as well as the Xochimilco residents. The San Románs go to Patricia's lake cabin in order to celebrate their shared ten-year wedding anniversary, unaware that Demetrio, whom they believe died after escaping from prison a year prior, is actually alive and well and is conspiring with his grandson, Ángel and Alma's young son Angelito, and the San Román grandchildren's nanny, Diana, to kill the entire family.
