John, Peter, Rob and Paul live on the same street.  Rob has an alarm system with motion sensor so he can monitor suspicious activity and one unlucky night his phone is out of battery when a sensor triggers. Luckily John Peter and Paul is connected too and discovers that the motion sensor in Rob house is activated. They gather and walk up to the house in order to figure out whats going  on. Feeling safe as a crowd they approach the house and after searching around they find the house unharmed and logs it so Rob and his family can see a faulty alarm went off.
