At the end of 2018, the Netherlands narrowly escapes a terrorist attack. Four Muslim extremists are planning to strike with Kalashnikovs and bomb vests during the Gay Pride in Amsterdam. In a holiday cottage in Weert, the terror suspects have an appointment with a weapons supplier. What they don't know is that these are undercover agents. The counterterrorism unit of MARSOF, the M-Squadron, is ready to overpower the terrorists.
