This summer, "The Totally Excellent Adventures of Mack and the D" will tell you the story of two buddies that help each other find ways to cope with being stuck in the 80's. When Mack and Deke are left behind by the time travelling Zephyr, Deke tries to make the best of the situation but Mack is heartbroken by the death of his parents at the Chronicoms' hands. He copes by drinking, making car models, and moping around while his beard grows. Deke, on the other hand, knowing that the fight isn't over, begins recruiting new SHIELD agents and creating a cover band. The 'Deke Squad' needs training though. They'll need it if they are going to finally stop Sibyl, who is using a computer nerd to transfer her still living consciousness from an old computer into a newly built, deadly robot body. Luckily, the squad will get some help. It's like, a totally tubular episode with those totally bodacious dudes Jay and Josh on this week's Agents of S.H.I.E.L.D.: Case Files.
