When genetically modified foods turn people into zombies, it's up to Manny to save the day...

Spirit of school shooter returns to wreak more havoc on Degrassi.

The Degrassi and Smithdale U students venture to Los Angeles. Despite issues at home, Ellie and Marco venture to L.A., as well, to visit Paige, who is now an assistant to an A-list reality TV star. Ellie then reunites with Craig, causing a reconnection between each other but bad timing and Ellie's guilt over avoiding her shell shocked father take their toll. Manny struggles to get a part in a movie, that Paige accidentally gets. Paige lets her good fortune go to her head and transforms into a demanding, obnoxious diva, insulting and belittling everyone in her mini-entourage, particularly Marco, which causes a rift in their friendship. A bad break for Paige and help from her ex Jay and the Studz eventually results in Manny's acting dream coming true at last.

During a graduation party, Spinner finds out that his girlfriend, Jane, cheated on him with Declan, and Emma starts a fire at The Dot. Wanting a summer vacation, Jane heads to New York with Fiona, Declan, and Holly J., where she finds an indie band looking for a female lead singer. Trying to comfort Spinner, Manny, Jay and Emma take him to a casino at Niagara Falls.

When you’re in high school, everything feels different in the summer – and for the students of Degrassi, this summer is no exception. Along with the record-breaking temperatures, tensions, romance, and friendships are on the rise. But while everyone hopes this will be the best summer ever, the city might have something else in store for them.
