Blasted follows childhood friends Sebastian and Mikkel, who are reunited for Sebastian's bachelor party. While Mikkel never matured past teenage laser tag-prodigy, Sebastian has grown into a career-obsessed workaholic who's using the party to schmooze a potential client. But when the bachelor party stumbles head-first into an alien invasion, it's up to Mikkel and Sebastian to reunite as the kick-ass lasertag duo they once were and fight back.
