To recapture something is to get it back or catch it again. If you were the zookeeper at a very disorganized zoo, one of your jobs might be to recapture runaway baby pandas.
The police might recapture an escaped prisoner, and when they do it they can call the act itself a recapture. You can also recapture things in a more figurative way — your dad might like to recapture his high school days by listening to 80s music, for example. The "again" prefix re- is added to capture, from Latin captura, "a taking."
