The show tells a slightly convoluted story about a series of killings in the 1980ies and 2017. A cop, who is thrown 30 years into the future, becomes part of a team working on solving these crimes. For a western viewer this is an interesting mix between well-known elements (cop show, enemies become best buddies etc.) and unusual elements: the time traveling just happens and is never explained; and even more so on the emotional side: while we do know the serious crime fighter show (think CSI, Criminal Mind) or the the comic variant (Castle), this is mostly sentimental. with a bit of comic relief and some action The show highlights the soppy elements of the plot, getting its emotional power mostly from all the family relations depicted (and not the love story). Even if plot and dialogue are sometimes a bit too formulaic and because of its sentimental bend the way it tells its story is sometimes a bit too slow, it is all in all quite an entertaining show
