You Are Not Alone is the first film of 2013. It was later remade.
A family goes out for a day in the park. While the father and daughter play tennis, the mother takes a walk but is attacked by a man wearing a Michael Jackson mask. The woman flees from her assailant and stops to rest under a bridge, but the mysterious man jumps her from behind.
The father and daughter then split up to look for the mother. The daughter gets tired and goes to sit on bench, but is approached from behind by her mother's attacker.
The father also finds a place to sit, near to a race track. Suddenly, the killer attacks him and they briefly wrestle before the father shoves the killer over a ledge. However, the killer suddenly wakes up as the film ends.
