As the semester begins at the boarding school Tuna Kvarn and the municipal school Holmered, Hugo, Caroline and Philip prepare for the year's selection in the Zebra Room.

A body is found in Svartan and several people go missing; an outrageous video clip goes viral.

The gap between the schools is widening as the police begin to dig into what really happened that night; Hugo has a chat with the Zebra Room; William is behaving increasingly stressed.

The annual relay between the schools ends, but does not turn out as Sara had hoped; Philip and Hugo are planning for the coming long weekend.

Preparations for Philip's home party and Carl's annual reunion party are underway; the work of the police continues, while the parties bring some people closer together and some further away.

Sara receives an unexpected visit from her past; William makes a huge decision; Philips' romantic plans go awry, while Isaac gets into the heat.
