The Time Card series follows the adventures and fortunes of three friends – Blue, Jesse, and Ellie – as they use the contents of their newly found case to travel to diverse and exotic places. Their middle school studies come alive as they interact with historical figures of their country and the world, while at the same time struggling to not change the timeline or upset the course of history. Trying to hide the case from present day bullies, the friends try to stay one step ahead of their arch enemies Ryan Johnson and Jake Barker, not to mention sinister otherworld forces that are determined to find the time card.
In the final episode of the first series, Jake Barker and Ryan Johnson steal the time card, and the three friends must hurry to find it (and Barker) before history is changed. The Daktars threaten again, and Commander Tam Harnik hones in on the kids and the time card.
