Darius is a young intern at a Seattle-based magazine and jumps at the chance to investigate the author of a classified ad seeking someone to travel back in time with. Along with Jeff, the staff writer, and Arnau, a fellow intern, the three go on a road trip to a coastal town. While Jeff just wants to chase after his high school crush and Arnau wants some kind of life experience, Darius spends her time with Kenneth, a man who believes that he has built a time machine. The closer they become and the more they understand about each other, the less clear it becomes if Kenneth is just crazy or if he actually is going to successfully travel back in time.
着力点很特别的时间穿越片。两处没看明白的地方。一部披着科幻外衣的情感开胃菜。以为故事会理所当然的发生下去，然而却出其不意。最好的普通人。《安全没有保障》：草根清新的小科幻。这是一个大小孩的 爱情奇遇记。从另一个侧面讲述的不同于其它方式的爱情故事。没有什么是安全的。建议躺着看。
