Like in the classic Groundhog Day, there are a few people trapped in a time look. There are a few parallels to groundhog day: it is also a good comedy, decent acting, and then, there is some quantum mechanics! To get out of the time loop, Sarah takes a few EdX classes, some quantum mechanics. She figures out that going into the wormhole with an explosive belt can bring you out of the loop. Similarly, in Groundhog Day, the time loop stuff does not make a lot of sense anyway. At least it is fun entertainment.
