With their now largely sexless relationship straining at the seams,  aspiring musician “Tim” (Dave Franco) and partner “Millie” (Alison Brie) move to a remote rural house near the school where she is to teach. The pair go for a country walk and during a sudden storm fall into what they think is a cavern, complete with old pews and a rather curious mural. Luckily there is a pool there so they don’t suffer from thirst before awakening in the morning and clambering out. No harm done, it appears, until poor old “Tim” goes to take a shower and finds he is no longer master of his own movements. He bounces around that shower cubicle like something magnetic is manipulating him. That’s just the start of this magnetism though, and pretty swiftly the pair are at their wits end trying to comprehend just what appears to be happening to them. When “Millie” pays a visit to one of her colleagues, she (and we) begin to put one and one together… It’s tongue is very much in it’s cheek here, there is some dark humour and an especially sticky scene in a toilet that might just make you wince! The ending isn’t the best, it sort of fizzles out disappointingly but along the way there is a bit more of a story to it, Franco and Brie gel well as they master the art of painful looking body-popping and the visual effects are creepy and effective. It’s a little bit of a slow starter, but once it gets into gear it hares along nicely.
