Now and Again (1999)

S1E13 I Am the Greatest

Theo drops a bombshell on Michael: he wasn't the first subject of this government experiment. Years prior, an army private underwent similar treatment and mysteriously disappeared without a trace. Now, Theo believes he has resurfaced as Maceo T. Jones, the undefeated heavyweight boxing champion. Michael's task is to get close enough to Maceo to collect a DNA sample, which will help Theo confirm whether this champion is indeed who they suspect. Meanwhile, Lisa begins her new career as a real estate agent, quickly realizing that the job is far more challenging than she anticipated.
